cooling system problem
Alright, right now Im running a Swiftech MCW462-UHT water block with a 226W pelt on it. I have the recommended meanwell psu for it, and (this is where i think the problem is) an Ice micro radiator. My processor is still running at 90 degrees F. You think if i got a bigger radiator (much bigger) it would be running at the temps i desire having a 226 watt pelt...when i first boot up my computer the processor temp is right around 32F (0C). Oh yes I am running a 145GPH pump in a reservior made out of gladware! I think the primary problem here is im cheap, but I just want to know what size radiator would be better and if you think thats the only problem...thanks! here is a pic of my computer so you can see how jerry rigged it is http://nerdmania.net/steve/computer/...t/IMAG0055.JPG

Swiftech reports those radiators will provide water temps around 15C over room temp with a CPU as the heat source. They don't recommend the micros for dual CPU use; much less a 226W pelt. I would assume your hoses and res feel noticably warm to the touch. You should DEFINITELY pick up a big heatercore (I favor the $19 1975 Chevy Caprice and the 1970 Chevy Blazer w/o AC cores cause they easily take 2 120mm fans). You could certainly see a 10C drop in CPU temperatures (more possibly) from switching to a radiator that can handle your heat load better.

Ya I KNEW this radiator was way too small, but I was cheap and got it for basicly nothing...I just wanted to make sure that it was what was causing it to be so hot, but if you say 15 degrees over room temp ( i think you meant F cause 15 degrees C is a lot) then this radiator is working damn good cause its about 80 in here and the processor is 90. Thank you ill look into heater cores from cars like i was planning on doing before!
SteveO p.s. If anyone has any more suggestions of what radiators you think are good send um my way! |

I'd recommend the 2-342 single pass heatercore if you can find a place to put it. (I don't know the relevant vehicle. "Blazer" I think.)
Because of the very low flow resistance of the MCW462-UH, other restrictions in the cooling loop, have a relatively large impact on the flowrate through the loop. With a lot of the newer more restrictive block designs, the WB resistance tends to swamp the resistances of the rest of the system, so surface area of the HC is the primary consideration. Assuming your plumbing is good, a big single pass heatercore will give you a major improvement. |
