Swiftech Releases Komodo HD5800 F/C Waterblock For ATI

I did not include a screenshot here because FurMark crashed just as I was about to take the screen but I can tell you that at 1.35V, 1030MHz/1250MHz with two HD5850s hooked up in CrossFireX with parallel water flow the peak temperatures on the VRM are 98C on card #1 (top slot), and 90C on card #2. The temperatures range a lot, with the hottest temperatures being observed on the middle VRM of the 3 since this is the hardest one to make contact with as there are no fasteners around the middle of the card width-wise. The two outer VRMs are both lower by 10C - 15C. Therefore, range is from 70C to 98C on all of the VRM on both cards. Tightening the screws futher does help lower the temperatures a bit still, but this is okay since the temps are completely under control now. There are no more runaway thermals.

All of the tests were done using FurMark 1.8 Multi-GPU, Xtreme Burning Mode, at 1920x1200 with no AA, Post Processing enabled. The load was consistent at 97% on each card, peak power draw was ~90 amps/120W, average was ~85 amps/115W. This power load will never be observed under normal operating conditions and under normal conditions the VRM temperatures never exceed 55C-60C from what I noticed.
