I was inspired by cravinmild here on OCN to use a traditional CPU cooler on a GPU. http://www.overclock.net/nvidia-cooling/1086286-complete-build-log-zotac-560ti-corsair.html

So I decided to stuff two Antec 620's into my EVO case to cool my reference ZOTAC GTX 480's. It wasn't easy....but props to cravinmild for his help!

I wasn't able to get complete photos throughout the mod, But i did have a chance to take some today.

UPDATE: See here for IHS removal

First off the only thing removed is four screws that hold on the heatsink on the GTX 480 as shown here: http://www.legitreviews.com/article/1258/3/

Then mount the cooler with zip ties

Now there is no way the Rad is going to reach the front of the case so I had to stack 2 fans in series + and shroud to give me space.

Both cards stuffed into the case

The Rads had to me rotated to fit

Mounted and secured

Done!

Have to say that it makes a huge difference not listening to the fans on these cards. I now have a virtually silent rig.

******UPDATED******

Successful 900/1800/2200 Overclock with a couple a cheap $59 Antec 620's with temps topped out at 49c and the VRM Temps via fans sensor at 47c

Fantastic stuff. Nice to see it worked out for you.

After doing these mods i cant go back to old school GPUs fans, far too loud.
Good pics, shows your gpu mod well, lol i didnt know you were going to do both of your cards cards.

Thanks for posting and lets see your benchies and overclocks.

Yep, I noticed that to. Top one peaked at 79, bottom at 73. I did have them dialed in within 1c of each other but took the top one out to take the pictures of the mod. I have to try to reseat again and or possible tube crimping that is causing it.

It was with a modest overclock of 825/1650/2100 as well.

Best part was....no fan noise!

Thanks, yeah I decided to do both after getting a second card from a chap here on OCN. $225 for a second card, same model as my first. Microcenter had the 620's on sale for $59 each.

What's cooling the VRMs/Memory though? Nice mod!

The stock fan is still connected and working to cool the VRM's. They also act as good alarms in case something happens with the 620's. At 100% rpms those things are like sirens. lol

I wish there was more room between the cards because in the process of bending the tube at the base, i popped off a screw head that is on the side of the assembly.

That sucks man. Perhaps switching the tubing for the top GPU cooler would help with temps, seeing as the 90 degree angle things are hurting temps. You'll also be able to extend your coolers farther so it a win-win situation

Good mod (+rep).

Feedback:
1) Have you tried doing a cross tying up of the zip ties? Perhaps this method will offer better contact pressure? See pic 1.

2) Is pic 2 below shows the current airflow? If so, the H50 is not going to be very happy.
Using the side panel fan as intake to feed air (for thermal dilution) to the H50 push fan might alleviate its unhappiness a little.

An alternate airflow pattern is shown in pic 3. This setup involves using PCI slot extractors/fans to remove those hot air.

Thanks for the info!
The airflow is as in PIC 2.
The CPU typically peaks out at 55-57c at 3.6ghz OC stressed.
There is a side fan on the Tempest EVO as well.

Farthest I got stable was 850. I haven't really pushed it pass that. Im only running an 850 watt PSU so im a bit nervous to push it more without a bigger PSU.

Thanks! Yeah the case is pretty cool. I'm always tearing into it. lol

They seem to work well. In would be happier with mod if the fittings were different so I could keep the gpu cover on. Would make for a much cleaner look.
