XPS 8930, another CPU fan question?

So, I have an XPS 8930 (i7-9700 non-K) that gets warm while gaming. From what I've read (and I think I've read them all!) the quickest/easiest swap seems to be the Arctic Freezer 11 LP. Anyone tried any others? Is there another option that fits as well and goes in as easily?

My thoughts...

First step would be to check CPU core temps at idle and under load.

This free CPU temp diagnostic utility works for me:  https://www.alcpu.com/CoreTemp/

The CPU torture test in free Prime95 works for me:  https://www.mersenne.org/download/

Next, improve the case fan cooling and recheck CPU core temps.  What I did:  https://www.dell.com/community/XPS-Desktops/XPS-8930-how-is-the-cooling-in-the-i9-9900/m-p/7508730/h...

Next, upgrade the CPU cooler.  I have not needed to do this.

Re: XPS 8930, another CPU fan question?

Thanks for the post. 

I've already checked the temps both at idle and under load. This morning, idle temps were 40-45c and load temps (an hour or so of Division 2) were 89c. I've seen temps as high as 92c, which from what I understand isn't all that unusual in this CPU as they run hot, but 100c is its TJunction.

I'll look into adding/improving case air flow, but I'm thinking that while I'm in there (and can't leave my house!) I may as well look at the CPU cooling as well. 😃

Case fans will help.  CPU cooler may help, especially if the new cooler uses heat pipes or the OEM cooler assembly is flawed (not likely with your temps since they seem normally high).

As a general rule... making and confirming one change at a time has its advantages... easier to assess and troubleshoot cause and affect.  And if an incremental change fixes the issue, you're done.

Do let us know how any CPU cooler upgrade goes so we can learn from that.

Agreeing with @GKDesigns that case fans is the place to start. If you get this Aurora R5/6/7 bracket, a 120mm fan will easily snap into the lower front intake position. Make sure your top exhaust fan is 120mm. Also note the "K" model blower style CPU cooler in the second photo, which can be considered, if necessary, along with the Arctic Freezer Low Profile unit.

Thanks for the advice, folks - I'll order parts in the next little bit and let you all know what happens when I add some case cooling.

This counts as schooling for the kids who are stuck at home with me, right? It should!

We think it should but my two daughters were never interested in such things at that age unless Legos count.  One of them went on to get a Masters in Mechanical and Aerospace Engineering, so don't despair and have faith... they'll surprise you in one way or the other.

Re: XPS 8930, another CPU fan question?

cpu 89C is too hot.  ok Intel GEN 9 CPU !

causes are simple here is a list. (thermodynamics 101 day)_

  • room is too hot, here it is 85f, on my beach house way hotter, is the room hot now. 95F is max on room.
  • CPU TIM bad, old and cracked TIM is bad TIM. (aka, Heat sink grease) replace it and do not use to MUCH.
  • lint on heatsinks and fans make them useless, clean the PC, really this is first and vents too. and PSU vents.
  • wires not hitting fan blades, do I really need to say that or stalled fans are bad? (PSU fan may be off)
  • Bad or dead or missing case fans. (bad system design or wrong fans put in)
  • what is is there, ?nothing ahh some PCs have bad BIOS,  and run fans too slow. upgrade BIOS>?

one can see clearly the CPU sends heat directly in to the case confines so case fans must remove this heat

or the CPU will overheat.  simple , fact is AIR COOL from room must enter the case and exit. or bad happens.

the top GPU cards can blow huge hot air into the case, not to rear of card to room but to the poor case.

that too is huge problem, now case fans must be beefed up to get that huge heat load out of the case.

all this is basic basics. end to end.

 

warning to the noobs, some fans do not turn on or go full speed until heat or power goes over 20 % of normal.

PSU do  that if new. (off until 20% of rated load is hit) or more.

GPU do that too if new, do you have GPU card? IDK what is inside YOUR PC> not me. and not told.

CPu all run full time, mine runs slow because BIOS sets it slow for my CPU runs so cool. by my efforts.

heat load 1 is here. then comes GPU heat  load.

Warning to the noobs, do not put thermal compound on top of your CPU fan as suggested in the post above!

@SaveMeJeebus 

For reference, here are my i9-9900 CPU (stock cooler) core temps under full load running the Prime95 torture test after upgrading to two 120mm case fans, which ramp up their speed with CPU load (still pleasant sounding)

The CPU freq can vary up to the mid-4000s.

I believe the recommendation is to keep core temps 15-20c less than Tj. Max.  So, 80-85c for my system.  Of course, I never run my system at full load.
