I spent some time last night with the system down to make sure the block was sitting on the CPU level. Which may be why my temps were a little elevated... as it turns out, it was... and it wasn't.

The CPU was not sitting quite level. So I corrected that and made the layer of Arctic Silver II a little thinner now that I didn't need as much. And I lapped the CPU (P4 was REALLY not flat at all).

While I was at it, I cleaned up the mating surface on the block on my GPU as well.

After all this and everything was put back together and the system fired up. I let it run with my usual load app (Folding@home) for about 15 minutes, which is more than long enough on MY system to level out the temps.

The temps, when stable were 2°C HIGHER than before. Now I know that people get in trouble for posting temps, etc. But this system has held a consistent temp for the last three weeks. Now it's holding steady 2°C higher than before.

From this observation, I have to believe that the water blocks are picking up MORE heat and the system can't get rid of it.

I am suspecting my pump as the major weak point as I turned the fans on my radiator to full RPM and it did NOT change the temps noticeably.

My pump is very slow as discussed in previous threads and is only about 60GPH with a really small head (like 2 or 2.5 feet)

Does this sound like I'm on the right track? …or am I hallucinating?
