Would this help or hinder...a watercooling question

[Amedeo602]

Theoretically, let's say Joe Schmoe has a waterblock which uses the lugs around the socket to affix itself to the CPU. This leaves the 4 screwholes around the socket open. Would screwing a fan into these holes so that air was blown onto the block help temperatures any?

Sounds like a interesting project ;) I dont think i can answer that but it may be worth it to give it a try ;)

The reason I asked...I could see where the temps could go either up or down.

Down: Obviously, the copper is being cooled so the water isn't as hot.

or

Up: Less of a delta T, so less heat is transferred...

I don't get it. If the water is cooler, the delta T should go up. Oh wait, the delta between the top of the block and the water. I don't think that should matter much because most of the heat will be absorbed from the bottom anyway.

Basically it sounds like you want to turn the base of an aircooling heat sink into a water block. Then use the sink as both an air cooler and a water cooler. My guess would be that the fan should show some improvement in cooling. You just want to move heat away from the cpu, I don't see as it matters whether it goes by air or water.

Try this. If you've got an old cpu heat sink rig laying around. Figure a way to mount it to the top of the block. Then turn it on and see what happens to the temps. I'm curious. :)

I don't want to add a heatsink, just a fan. And the delta T i'm referring to is that between the block and the CPU. The block would benefit from the fan while the CPU wouldn't get nearly the benefit. the Delta T would be greater and the water would pick up more heat (Newton's law of cooling). Follow me?

Basically I'm trying to cool the block more so that it would (theoretically) absorb more heat from the CPU and lower temps.

your temps may change 1-2c lower just because you will be blowing air in the cpu case where that gage is


I wouldnt expect very much improvment though

however I have heard people do this as a backup if your pump goes out
the temps will be high but not high enough for the die to fry (unless your under load)

My idea (I apologize for the crappy drawing, but I'm in a class and was forced to use M$ Paint):

That's probably true. However, the koolance i just ordered has a probe inside the block so I might try this to see if the block itself goes down any substantial amount (i'd expect a couple degrees difference in the block)
