Hey guys can anyone tell me if they have seen or actually put a aftermarket cooler on the XFX** Radeon 4890? Im asking specifically about the XFX version as I have heard its nonreference...

I have also heard 1 case of a guy not being about to remove the sink from the vrm cooling plate...

http://www.overclock.net/ati-cooling...ml#post6656378

He had the Radeon XFX 4890 HD XXX

Im runningg the non XXX version so hoping I dont run into that same problem, but have no idea if I will or not?

So +Rep to anyone who can give me insight into this!

THX!

P.S. Plan on using the Scythe aftermarket VGA cooler.

**Double posted on the ATI Graphic card forums, didn't see the cooling forum**

P.S. Use the VRM-R1 & -R2 on the lower & upper cards respectively to avoid clearance issues.

Unless you get the VRM-R1/R2 you won't be able to do any heavy stress testing like ATITool, Furmark etc.. because the VRMs will overheat in a matter of minutes.

Other than that though you should be fine. The highest temp I've ever recorded during normal use was 113C after an hour of Crysis. The max is 120, but mines gone up to 140 without crashing.

Oh and XFX can't sell you an extra cooling plate, I've already asked.

This. As long as it's reference design (posting pictures of it would be your best bet, or comparing it to pictures already online). I'm trying to fit a Thermalright VRM-R1 into my budget, because I can get my 4890 GPU to 1GHz but I can't test long enough to be sure it's stable - all because my VRM temps skyrocket to almost 120C in less than 5 minutes and I had to abort the test.

I mounted an Accelero on one of mine (http://www.ncix.com/products/?sku=32...ctic%20Cooling). It makes it a LOT bigger, and depending on your case/mobo combo, you might be limited in what card is your primary. My Accelero-ed card will ONLY fit in my top slot with my new case/mobo. I cannot mount it in the 2nd PCIE slot. I had plenty of room in the Cosmos 1000 case + MSI Eclipse board, but much less with an Asus P6TD Deluxe mobo + HAF932 case.

Install was NOT fun. LARGE pics below (too lazy to resize) :







But after all the trouble of installing that cooler (it's a painful install), I accidentally discovered the best air cooler for 4890s: the Coolermaster HAF932 case. It has a GARGANTUAN 230mm fan that blows directly onto the video cards. No joke, it shaved a full 15C off my idle temps on BOTH 4890s.

Thanks for all the help! Really appreciate the pictures!

After some thinking and review of many posts I decided I would go with this:

(2x) Thermalright T-Rad2 GTX Heatpipe Slim VGA Cooler with Dual 92mm Fans for ATI and Nvidia
http://store.yahoo.com/svcompucycle/t-rad2gtx.html

Thermalright VRM-R1 (Side-Panel Type) Voltage Regulator Heatsink for ATI 4890/4870
http://store.yahoo.com/svcompucycle/vrm-r1.html

Thermalright VRM-R2 (Tower-Cooling Type) Voltage Regulator Heatsink for ATI 4890/4870
http://store.yahoo.com/svcompucycle/vrm-r2.html

I figure i'll use the VRM-R2 for my top card and let it sit next to my processor fan +a 80mm fan of its own. And then I'll use the VRM-R1 on the bottom card and let it be cooled by fan on the side of my case. We'll see how it works, im supposed to get then in 1-5days! I'll post pics.


+Rep to all who helped thanks!

I got my all my VGA Thermalright stuff from SVC.com as well, good etailer imo. Just remember, if you use the VRM-R2 on the upper card, make sure you do not have a 38mm HSF, you WILL run into interference problems. Trust me on this one, I tried .

Thanks for the advice lone, Can't wait till it all gets here!

Have you tried using a Pull setup with your HSF? I heard it could cost you 1degree or so but if its just gonna go to waste in your room... why not =)

LoneWolf3574

Yes I have, and with that 38mm HSF I really haven't noticed the temp cost. When I did change over to a pull setup I also changed my TIM to MX-3 from AS5 and I've seen a 5C drop in my temps across the board. I was going to try doing a shroud for my HSF and had already gotten the sacrificial fan (Kaze 1000) but now I don't think I will since it will overpower the 1900rpm Slipstream exhaust and burn that one out.
