Making a home-made waterblock: Waterproof a GWFOP32-1?

[CZroe]

I'm REALLY cheap. I'm trying to build a budget watercooling setup using non-dedicated parts. (ie, fish tank pump, auto heater core for radiator, etc) I've got the radiator, and I know what pump to buy (From Pet's Mart). The problem is, it'sa dual CPU system, so buying two waerblocks could be expensive. Also, nothing seems to be made for a guy that's not using peltiers My guess, it that just lik HSFs need long, flat, thin fins to increase their surface area to the air, why don't waterblocks use the same principle? I mean, the try to dig the chanels for the water in tight little rings to get more surface area on the block its self, but wouldn't running it across the increased area of a real heat-sink be more efficient (and cheaper)? I know there may be some waterflow problems beacase the fins weren't exactly made for letting water flow freely, but with the exit pipe on top it should always get the hot water out first anyway. Of course I know the dangers of building my own waterblock (Leakage, piss-poor CPU frying performance, etc), but I want to do it right. What if I only sealed the inner portions of the heatsink and left the outer portions exposed to the air for in the event of a pump failure? I have a program designed for this board that can severely throttle back the FSB speed and start CPU fans when certain temps are reached.

Anyone that has made one another way have any hints or other ideas? Thnx!

From my personal experience watercooling without a peltier or a chiller is a waste of time. Yes, water can handle a lot of BTU's, but heat soaking is a problem and without some cooling help the CPU will steadily go up in temperature until the system locks. Room temp watercooling isn't very efficient...

Thats just not true...........

OK, it must have been a dream then... or a nightmare!

It's dual Celerons BTW. They can take a bit of heat because they're .21 PPGA CPUs

I am running an Athlon 1ghz @ 1.4ghz with a vcore of 2.0. Thats somewhere in the 93 watts range as calculated by Radiate(nice little program for calculating power usage). Your two celeron's are probably less total than my one processor. I am running an AquaStealth II with the AquaCoil upgrade installed in a 7237. I have decent ventilation and plenty of intake for my AquaCoil (it runs the Panaflo H1A, not as quiet but still decently quiet). I can idle just several C above ambient, and top out at 43C running full load @ 1466 (ragged edge of stability @ 101 watts). I use to only get 1333 out of this chip with an Alpha PAL / Delta combo and it use to max out in the low 50's with that and only 1.90 vcore (81 watts). So can a watercooler cool efficiently? Yes.


...........edit.............
I have made a homemade waterblock, and it worked ok. I always wanted to try encasing a PAL or other heatsink. I just don't have the welding talent to do so and I really didn't like trusting just silicon. But maybe something like JBWeld would work to seal a plastic top and the barbed end. Might be fun to experiment. I think your standard copper waterblocks are efficient enough though to feed the radiator. I hear heater cores work even better than the AquaCoil (Cube style) radiator that I use. It's the radiator that will really determine the efficiency of your watercooler. It's what removes the heat from the water. Cooler water absorbs more heat and/or keeps the waterblock cooler.

Remember, always test it for awhile outside your case before you install it. That will save headaches. I use just a small amount of Purple Ice, which is like Redline's Water Wetter. I tried antifreeze, more to make it looks cool than anything, but it was worse than just a small amount of Purple Ice.

Have fun...........
