Here are some quick test results I did tonight:

TBH they were pretty close since the stock plate is larger but has no fins for dissipation. These are just much nicer looking and all around easier to deal with.

Hmm... I would prefer (and pay more for) copper due to how hot the HD4000 cards get. Also since it is a dual slot card to begin with, I would have liked these to be much thicker. Perhaps iandh could release two versions of them?

There's no need for copper or larger sinks. Did you not see the thermal results he did? The temps are perfectly fine.

I've had the same problem convincing people with the 8800GT sinks and the 9800GTX ones as well.

There was a test early on when I first introduced the 8800GT sinks, and a user actually got better memory temps with my aluminum sinks than he did with the forged copper enzotech sinks. I'm not saying that would happen in every instance, but either way they seem to work quite well.

Mine are still running strong.

Thanks, your test results look very good. I used your sinks on my old 8800gt + HR3-GT and was very satisfied. I just wish these would've been available two weeks ago when I setup my 4870.

Are you considering cooling the Pulse/Vitac chips also?

nice might have to pick some up soon

I have a few questions concering these VRM coolers and whether or not they will help my situation.

I have a VisionTek HD4870 with an Accelero TiwnTurbo and no RAM/VRM sinks on. I had great difficulty putting on the sinks because the thermal tape was of poor quality so they remain without.

After monitoring my temps with RivaTuner I noticed my VRM idled at 66C, hit 110C at full load, and peaked at 114C briefly. I am told the critical temperature for the VRM is 110C. I do not feel I can continue to game safely with these temperatures.

Will I see a dramatic improvement with these RAM/VRM sinks? What is considered safe temperature for this card?

I have optimal air flow conditions in my case and run the TwinTurbo fans at 75%.

I saw these on Petras and Xtremesystems....great job iandh. THese sinks look to be of superior quality.
Keep up the great work!

114c youll kill that card if you not carefull. need need to get to about 80c or so
