Watercooling a 5850

dfour · 14 Jul 2010 at 14:48

I have a 4890 Wc with a danger den maze 4 (I know its old but it works well). I have just purchased a 5850 witha full block (second hand) and was wondering if its better to use my older maze 4 and the heatsink plate and fan from the 5850 or stay with the full cooler?

I have always been in the belief that a dedicated core cooler is better than a full face block.

Hi, l'm using a full cover on my 5870 at 885/1275MHz in my h2o loop > rad > res/pump > cpu > gpu > rad. At this moment the gpu is at 30'c idle, my living room was at 25,C weekend gone, its where my PC is. Playing BC2 the gpu never went over 44'c, and don't for get it gets the warmer water as the cpu gets cooled first. :cool:

Go full cover better for overclocking the gpu..

Full cover I think. The stock VRAM plate on the 5850 isn't that good in my opinion. You could get away with it if it was more like GTX4** plates or the Swiftech ones, but as they are, I'm not so sure (waits to be proved wrong).

If you've got the full cover, try it and see.

I had a core only block originally on my 5850, with heatsinks on the RAM and VRMs. Then I switched to a full cover block and core temps went up a bit, VRM temps quite a lot. I was able to remove the fan pointed at the heatsinks though so I was happy to stick with the full cover block.

well i got a MCW60-B this morning and its sitting on my desk waiting to be installed but think i'll need to get bit more tubing and so water additive though.

This is for a Direct CU 5850 which has its own VRM heatsink and no Ramsinks ( i must order some of them too)

I have a Aquaextreme MP-1 (same externally as a Maze 4) on my 5850 and have no problems at all. I have Zalman ramsinks on the memory and made a heatsink out of a old Pentium (zif socket) cooler for the VRM's.
