Low Profile Cooler recommendation for 8800gt???

post #1 of 8
Thread Starter 
I'm needing a really low profile cooler for my OC'd EVGA 8800GT.... it's installed in my Dell XPS420 q6600 the space between the top of my card and the bottom of my cpu is only about an inch been looking on my own for about the last hour and just am not finding what I need....

...and no, the card can't be moved down any, it's as low as it can go already.

was hoping some of you all have been here and done this already... it's not a new computer or card obviously, but it still has some good life left in it I think.

really needing some help...

thanks to anyone who can help out!

That video card already has a single slot cooler, that's as small as they get for card's like this.

If you used a different heatsink you could make it work, something like this?

Look's a lot smaller then that dell one

yes, the card (video card) already has a cooler, it's the stock EVGA cooler that came with the 8800gt it's also not cooling sufficiently.

you linked me with a CPU cooler... did you think I was looking for one of those? or are you meaning to replace the GPU cooler with a CPU cooler?

or am I just up too late at nite for my own good?

GPU is in the middle so something like this can work fine

First off, did you try disassembling it and removing the dust that could have built up in it? Also reapply some thermal compound to it too. Id try disassembling and dust removal. Because that can caused it to cool insufficiently. they arent screwed together. You have to pry the fan/heatsink cover off very carefully with a small flathead screwdriver or a razor blade. Once you do this, make sure the metal cover isnt bent, and if it is, rebend it, and itll expose the whole heatsink fin assembly and fan. This is where the dust collects, I swear heatsinks are like an air filter.

^this.

Let me add my own comments below.

Yes, your computer still has some good life in it. A Q6600 (especially if overclocked...which is usually not possible for a Dell but as yours is an XPS, perhaps it could be?) is still not bad.

To control the temperature of the 8800GT, there are 3 measures:-
1) Due to the fact that your card is old, dust must have accumulated inside. Take out the card and use compressed air to clean the fins. Additionally, take out the heatsink and re-apply thermal paste.

2) The card is located right underneath the CPU cooler. The CPU cooler exhausts its hot air out and there is no immediate extraction of this hot air via the rear of case. Hot air gets accumulated in that region fairly quickly. This means, much of this hot air is being sucked by the intake fan of the card. See pic 1 below.

To improve, just install a 92mm or 120mm fan to the case rear to exhaust. See pic 2 below.

3) It seems there are 2 versions of XPS420. One has a front panel with vent openings at the lower part (see pic 3 below) and one has not. If yours has the vent openings, I suggest you adding a fan (see the 2 suggested locations as shown by the 2 green rectangles in pic 2 to intake more ambient fresh air for the card's fan.

Lastly, I do not recommend you using an aftermarket cooler like the Zalman. Because it dumps heat inside the case and this calls for careful and delicate thermal management which, IMHO, cannot be handled well in your Dell XPS420.

yeah, been there and done this, have done it twice so far in the life of my computer, usually is good for a degree or more while under load.

although I wouldn't use compressed air as it can be full of moisture, actually I use a shop vac that I can reverse the airflow on (no it doesn't blow the dirt out), is a good way around the moisture problem.

BTW they sell compressed air in a can that is guaranteed to be 100% moisture free.... I used to have some but found my shop vac works much better. Here's some right here at Amazon

yeah, my 420 has those front vents.... and actually there is a fan right inside there too, all ducted up nicely for extra ventilation.... unfortunately I can find no way at all to control the fan manually or with any third party app if anyone knows I'd be highly interested!!

I tried speed fan a couple years ago, and went to Rivatuner. it does a great job of monitoring and controlling my gpu fan, couldn't run my computer without it. Gpu Monitor is also quite awesome (works with the Rivatuner stat server, I used to use Everest but since discovering GPU Monitor - no longer) I have that set in my sidebar with all the bells and whistles, and the fullscreen monitor too for everything I run to keep an eye on things in realtime.

also have since zip-tied a case fan to the inside rear of the case and added a cool little adjustable fan I found, it slides on rails so you can position it right where you need it, I put it underneath the gpu blowing on the underside of the card... this has worked out so good, I'm not in such a hurry for a real cooler now. I was getting temps of up to 84c even with 100% fan on. now, after these two little cheap mods (didn't even have to pull my video card out) it won't go over 64c even with my heat blasting in my room.

windfire... so you say the Zalman's are pretty hot, eh? seems a bad trait for a gpu cooler... how much would you say? ever tested and taken some temps?

thanks people, is good to know your experiences and what you all have been thru.
