Studio xps 435mt - changing case.

It looks to be standard micro-ATX, and thus is compatible with third-party micro-ATX and ATX cases.

Perhaps, however, you could solve your problems through use of quieter fans, rather than a new case. I pieced together a homebuilt in an XPS 7100 case, and it is very quiet, using a third-party 92mm exhaust fan, Seasonic 520-watt thermostatically-controlled power supply, and Silverstone CPU cooler.

Ok, would this be easier to do?

I just want to keep the temp of cores down a bit and reduce the noise. Could you please give some examples of what I would need, product names etc. This is my first time in upgrading anything more than memory or an hdd in a pc.

Thank you.

I can personally vouch for this power supply. It has a quiet, thermostatically-controlled fan, is standard length (important for some cases), and meets 80 Plus Bronze for less heat. Case fan is Antec Tricool 92mm, while CPU fan/heatsink is stock Intel. You might start off with the power supply, which in my experience is the biggest contributor to noise.

Also check that you don't have a rogue process boosting your CPU usage to very high levels, which will cause your CPU fan to speed up.

Hi thanks for the reply rdunnill, I will look into those parts. Are they all pretty simple to swap out for new ones?

Did you mean the case fan in my machine is the Antec Tricool or that is one I should look at getting?  

I checked all the running processes, but nothing was really using much power. It used to be that I would have to be doing something very heavy like video or music editing for the pc to become noisy. Now even simle tasks like IE or playing a video in WM seem to heat up the cores (coretemp) and cause the machine to become noisy.

The noise has become worse in the last year I would say. I guess thats to be expected withh machines as the age? The only thing I have changed is an upgrade to Win7 in the last 6 months.

The Tricool is what you might look at getting. The parts I suggested should be simple to swap in, but I'd suggest getting cable ties if you change out the power supply.

No, machines don't necessarily have to get noisier as they age, provided dust build-up is periodically cleaned out.

The Antec is available on Amazon UK, but it's expensive. I suggest a good-quality four-pin fan instead.

For starters, I'd inspect inside the case for dust build-up, if you haven't already.

I will probably be buying from overclockers.co.uk which is apparently a UK new egg equivilent. Not sure they do that fan though.

Thats great. Will the power supply come with all the right connectors, in fact will all psu's? Im from the uk so have to source the parts here.

My core temps are 60 when idle, and with the noise I know something needs to be done. I will start with the fan and psu and go from there.

As I said I checked in taskmanager to see if there was a rogue process or something straining my system but nothing seemed to be.

Could I just ask,

Is the PSU you suggested significiantly better than the stock one? If so how?

Also I seem to have one case fan at the rear extracting, One Cpu heatsink extracting, and the psu fan extracting. Shouldnt there be another fan to pull in some air rather than just the three listed above extracting?

Thanks for your replies.

I couldnt find how to connect it to the power supply. I swapped it with the stock fan and plugged it into the motherboard. the power connecter that came to connect to the power supply. I couldnt find where to plug it. I didnt have any of those type of connecters, nor were there any being used by anything else.

Please tell me where I may have gone wrong.

Hi Just to say I bought the antec fan as suggested. It only worked on its highest speed, yet still seemed quiet slow. When using low or medium setting the fan didnt go. I sent it back. I am not sure whether to get another one, to see if that one was just faulty or could it be my motherboard didnt have enough power to run it?

It's supposed to be powered directly by the power supply, and the lead to the motherboard is an RPM indicator.

The four-pin connector is a Molex connector, which in this case is an adapter connected to a standard three-pin motherboard fan connector. If you remove the Molex adapter, which apparently you did, the three-pin socket should plug into your motherboard. However, that doesn't seem to be working.

The power supply should have at least one spare Molex connector handy; those are fairly big and have four female connectors.

Hi

Thanks for the reply.

Yes thats exactly what I did. 

I double checked last night, My psu doesnt have any molex connectors that I can see. It has one spare sata and one othe type connector that I dont recognise

Isit possible that my psu doesnt have a molex lead?I

I bought this fan as I was recommended it for this specific dell model earlier in this thread.

Any ideas?

The fan should work plugged into the mainboard.

I'm not familiar with the 435 MT, but I'd be surprised if the power supply had no Molex connectors.

Maybe Speedstep can post a picture.

It's possible your power supply doesn't have any spare Molex connectors.

I've never seen a power supply without any at all, but that doesn't mean that they don't exist.
