My new Alphacool Nexxxos v2 7950 water blocks.... agh. VRM temps skyrocketing. - Page 11

Really? The MCP655 puts out 3.2 psi of pressure. Black ice gtx is 1psi, Siwftech MCR320 is probably around .5 ish psi, each GPU block is 1psi. So that equals roughly 3.5psi which is more than the head pressure of one 'MCP655

I'm willing to bet that's wrong and it'll be overkill for just 1 loop of 2 GPU's.

All I know is that my temps improved when I added a second pump. That's all I'm saying. Not trying to tell you that you're wrong or anything like that.

Don't forget the TS has two 655-B's, so no 'setting 5' on his mcp's.
On setting 5 the mcp's produces the same head pressure at twice the flowrate compared to setting 4.

Also, you have the heatkiller blocks for your 7970's. These direct all flow over the VRM section which makes the VRM temps way less viable to low(er) flow.

Didn't notice those pumps didn't have "Setting 5". My bad. tongue.gif
