Re: XPS 8930, possible to install a front case fan?

I did not have any fans prior to this project. I bought the Alienware R5/R6 upper exhaust fan from the auction site just for the bracket, so I can change my upper exhaust fan from 92mm  to 120mm. I bought the Alienware R5/R6 lower front fan and bracket, thinking it would be a simple install, but when I connected that fan via SATA, it screamed at 2,000 rpm. The Noctua fan I have connected temporarily has the "Low-Noise Adapter" in the circuit and is quiet.

This is the link to the dust filters: 120mm Dust Filter

These are for 120mm fans. If I use the Alienware R5/R6 bracket for the lower front fan, I need some way to mount the dust filter.

The three fans I purchased based on my understanding of your previous recommendations are:

2 - 120mm Noctua NF-S12A PWM

1 - 120mm Noctua NF-S12A FLX

I was planning to use one PWM for the top exhaust upgrade, one PWM for the top front, and the FLX for the lower front position. Please feel free to make recommendations to the contrary.

The "tabs" you refer to at the top front fan location where the hard drive basket used to be are very close, but not quite lined up well enough to mount the fan and dust filter. Also, I would like to mount that fan 'offset' as much as possible so it is blowing air to the back of the case, and not into the PSU 'dead space'.

I understand I will be shaving the pins on the front bezel to clear the dust filters.

I thought I was going to start this project today, but life got in the way. Therefore, I am still interested in hearing any recommendations or suggestions for this project. Recall I am also upgrading the PSU to the 850 watt Seasonic. I have read through your "liquid cooler install" thread several times, and that is very helpful. I have also seen the recommendations from 546insp, to which I will pay heed.

Thank you for all the help and information.

Just stick with 120mm fans and you will be fine. My front Arctic PWM fan is tied in with the top rear one and goes the same speed (it came with a splitter wire) and it is all very quiet. It normally runs at 80* F at the top of the rear one (coming out) and goes to 90*F MAX with heavy duty programs. Double sided tape works very well for mounting in PC's. My front fan is mounted with tape and weather stripping which knocks out the "noise causing" vibrations. MAKE SURE ALL THE FRONT AIR COMES FROM OUTSIDE.

Sorry Dell630i I somehow forgot to answer your question.  Hope it's not too late.

I went back to the old posts you looked at and I could see how you got confused and ordered those 2 Noctua PWM fans.

I know you considered using the OEM fans that came with the correct fan brackets you ordered and the only way to use those effectively was with the TOP FAN PWM motherboard header because as MrArcher said, you want nothing to do with those fans spinning at full speed.  So that's why I suggested getting a 4 pin PWM splitter so you could run that OEM PWM fan modulated, as well as fixed fans off the other legs of the splitter.  I think I also got off tangent a little and suggested how to mix the different types of fans in combination using molex adapters and the TOP FAN header which totally must have confused you. (I read it and it confused me so I cleaned things up)

In another post I suggested using the OEM fans first and trying them for noise tolerance.

https://www.dell.com/community/XPS-Desktops/XPS-8930-possible-to-install-a-front-case-fan/m-p/623902...

I compared the Noctua NF-S12A PWM fan and the Noctua S12A FLX (fixed speed fans) you ordered and said that these fans are better as intake fans because they move as much air at lower speeds and with less noise as the another Noctua PWM fan would if it ever were to reach maximum speed 2000 RPM.  I might have suggested upgrading to the PWM fans somewhere along the way, but that was wrong.

So the best way to approach your final fan configuration would be to use 3 Noctua S12A FLX fans if you are going to dump the OEM fans that came with your brackets.  

First off, we have an open TOP FAN header.

1) We figured you would use the Noctua FLX fan at 1200 RPM fixed at the top exhaust position
2) We would ideally use the same Noctua FLX fan at the upper front intake and lower intake fans as they are quiet and moved air at a constant rate versus the PWM version.

Since we have a open TOP FAN header, you can connect one, two or all the fans to that TOP FAN header as we know it will run at fixed speed on that header.  You would need a 3 pin splitter, and even those 4 pin splitters should work as the 3 pin fans would run at full 1200 RPM speeds.

The option is available for you depending on the splitters/Y adapters you have to connect any of these fixed fans to the PSU using molex to SATA power adapters that come with the Noctua fans if the connectors are close by (especially at the front intake postiions) rather than running them to the top of the case where the headers are.

If you already went the PWM route with those intake fans, your machine should be fine and there is no reason to switch them as it is running really quiet as it pulls air into the case at those lower 700-900 RPMS.  High CPU temps would be the only reason to make any changes.  With those fans in place you have created a balanced pressure case (more likely a positive pressure case) with better airflow, which is the desired end result of adding the front intake fans.  

Also I hope you considered the 92mm fan bracket at that upper intake position if you haven't already mounted that 120mm fan.

Then there is the case swap discussion we are having here as well.  Very applicable to you since you have that killer machine with new i9-9900K CPU and the GTX 1080.

Not a problem Hanover, and it is never too late. I did an exploratory venture into my PC this past weekend to make sure I know where all of the wiring connections and routing go (took a lot of photos) for when I swap out for the Seasonic PSU. I think I have that all figured, and while I had the GPU pulled and out of the way, I started playing with the front fan placement. Long story short, after much consternation, I am going with several of your recommendations. I am going to use the Aurora R5 bracket for the lower front position and a 120 mm Noctua fan (to be determined). Also, because those tabs in the upper front location are in the absolute worst possible position for drilling holes, I am going to mount a 92 mm fan into the HD basket and see how that works. I ordered a Noctua NF-A9 FLX fan for this purpose (should arrive before next weekend). Then I have the Aurora R5 bracket for the top exhaust fan to replace the 92 mm stock fan with a 120 mm Noctua.

If I understand what you are saying, I should use the 120 mm Noctua NF-S12A FLX fan in that top exhaust position, plugged directly into the MB, with no "Low-Noise Adapter". For the top front position, I will have the 92 mm Noctua FLX fan mentioned above. For the lower front position, I will have to start with a 120 mm Noctua PWM fan in the Aurora R5 mounting bracket. I can replace this with a FLX fan later, if necessary.

I currently have two 120 mm Noctua fans temporarily wedged in the front fan positions with rubber gasket strips. I am picking up power with a SATA to PWM fan splitter cable. I also have the "Low-Noise Adapter" plugged into both fans. I was originally planning to run a splitter off the MB to power the front fans, but now after I install the Seasonic 850, I can get power for the front fans with either SATA or Molex adapters. I don't see any reason to use the MB for power.

One more note: since I am not drilling any holes and running bolts, I needed to come up with a mechanism for mounting those dust filters I linked to up-thread. I used some magnetic tape and trimmed it neatly, which is going to work out just perfectly.

Good choice and easy.  You can go straight to PSU as its right there.

Option and for future reference: You should have a 3 pin Y adapter with the Noctua fans and you can connect both of those fans to the TOP FAN motherboard connector.  Both running fixed.  If you go direct to the PSU, use molex or your SATA to PWM fan adapter/splitter which works great for 3  pin fans as well.

You can put a LNA on the 92mm fan if you want, but I think it will be fine after looking at the specs 17.1 dBA at 1600 RPM.. (~ same dBA as the 120mm SA12 fans)

 


For the lower front position, I will have to start with a 120 mm Noctua PWM fan in the Aurora R5 mounting bracket. I can replace this with a FLX fan later, if necessary.

Your SATA to PWM fan adapter/splitter is perfect for what you are doing here.  The PWM fan will run fixed at 1200 RPM  just like the FLX fan would.  PSU is right there.

Option and for future reference if you are without those SATA to PWM adapters: You know you have those 3 pin to molex adapters with those other fans. In a pinch, you can use those to connect any PWM fan to get fixed speed by cutting off the side to accommodate the wider plug, same with LNA. (Thanks AlienBlaster)

You can take those LNA adapters off  if those are the NF-S12A fans, at 1200 RPM fixed they should be real quiet.   The drop from 1200 RPM to 900 RPM with the LNA does almost halve the noise with only a 20% drop in airflow so I can see that as well.

In regards to the dust issue, I pick up very little dust on the upper intake fan position with the fan filter I have there.

I do pick up a lot of dust on the lower intake fan.  A LOT.  I am constantly cleaning that front filter over the blowhole.  That’s probably why none gets to the upper one!

Another reason I would never install a top front fan. The top one just blows air that hits the PSU cage, drops down, goes back, and then up (if it ever makes it that far), not to mention you have to permanently remove the top HDD cage. It's much better to just block the top off and draw from the bottom so the bottom one draws from OUTSIDE.

Re: XPS 8930, possible to install a front case fan?

Apologies for resurrecting this old thread (I have been reading it and it is very informative, so many thanks to all the contributors!), but I can't seem to find the bracket needed to install a 120mm fan. I've searched on the big auction site and on Google, but all I can find is the fan itself, as opposed to just the bracket. Does anyone have any suggestions? Thanks

They are still  there on the auction site.

Search Alienware Front Intake fan

Part number is 7M0F5, make sure bracket is included

Once you have it, then go here

More updated info on that post

 

Edit:  Try Alienware front case fan, seems to work better

My PC also came with the 92mm top exhaust fan. I will be replacing that with some kind of 120mm fan. I see your point about moving air volume, and none of the fans that I linked in my post come close to the ~149 CFM. I will have to cogitate further.

I am also misunderstanding the PWM Y connector. I thought that there was one 4-pin connector for modulation and one 3-pin connector for power only at full speed. Maybe it is one 4-pin connector for sensor reading, and both connectors are modulated?


You want nothing to do with the stock fan it if is turning fast enough to move 149 CFM.  The noise will be an issue.  But if your CPU and case temps are reasonable, the stock fans, as reported by Archer, are not noisy enough and the GPU and CPU cooler fans might be the loudest fans in the case.  

The way the PWM Y connectors work is that they supply the same voltage to both PWM fans but you can only monitor the speed on only one fan.  You can use a 3 pin fan in the 4 pin connector but it will run at 100% since it isn't being modulated without the 4th pin being present.


OK, these are the project items that are in hand on the way. My current plan (subject to advice herein) is to put the Noctua NF-S12A FLX 3-Pin fan in the top exhaust position using the Aurora R5 top bracket. I got two of the Noctua NF-S12A PWM 4-Pin fans for the front upper and lower positions that I will 'daisy chain' from the mobo top fan header with two of the PWM 4-pin fan splitter cables (not sure which one yet). I will not use the lower front fan Aurora R5 snap-in bracket to mount the Noctua fan. I got rubber gaskets for the intake fans on the inside of the case and the mesh filters on the outside of the case to try to get a good seal. I will block off any extraneous air intake to ensure I am not recycling hot air from inside the case.

 

 

 

 


So what size are all these fans? I hope all will be 120mm


 

 

yes, all 120 mm

Re: XPS 8930, possible to install a front case fan?

Hi, i really thankful for all of you sharing your idea and experience in this topic,

it's does help people like me.

i would like to share my experience too, my objective are cooling performance first noise reduction come later.

1. Replace Dell stock cpu cooler with NOCTUA NH-L9i by replace the stock mobo backplate with any LGA 115X mobo backplate. Not much gaining from here like reduce around max 3°C? LOL! but noise reduction does have a huge different even NOCTUA CPU COOLER FAN spin at max 2500 rpm.

2. Replace Dell stock 92mm top exhaust to COOLER MASTER SICKLEFLOW X 12 and adding another 2 COOLER MASTER SICKLEFLOW X 12 to front top and bottom. Manage to gain like -8°C to -10°C by adding these (GPU only gaining minor improvement i am not sure why but is ok because my GPU max temp only stay at 75°C while running at 2000+ mhz before adding fan), COOLER MASTER SICKLEFLOW X 12 are static 2000 rpm fan, fan will spin at 2000 rpm even computer stay at idle LOL! so it will be noisy!

You guys might wonder why i choose COOLER MASTER SICKLEFLOW X 12, actually this is just a temporary fan for experiment lol because this fan are cheap! i am waiting the arrival of 3 NOCTUA NF-A12, hopefully i will be able to reduce noise by using NOCTUA NF-A12 and still get the same or even better cooling performance, i am from MALAYSIA the shipping fee from ebay are too expensive for me to get Dell stock 120mm top exhaust fan and aurora r5 front bottom fan with bracket, i better spend these money to get better fan like NOCTUA NF-A12 or CORSAIR ML 120 PRO.

Re: XPS 8930, possible to install a front case fan?

Those magnets are a bad idea, get some thick double sided tape. You are just transferring vibration noise and allowing air to whip around the sides and recirculate.
