Custom 62mm TEC Water block - Page 62  

post #611 of 680
awesome, thanks for the input. I'll have to pull out the heatsink and measure out the mounting holes so you can compare to your blocks. I currently have one of the mounts that came with an old zalmon copper flower heatsink attached to the 6x6 heatsink, so one of the standard cpu mounts does fit. I just don't know which one it was, hehe.

Correction: the zalmon copper flower itself is attached to the cold side with a custom aluminum cold plate in between. was experimenting with air chilling.

Hope you have a really efficient air cooler . Honestly because I have a 12" x 8.5" x 1" heatsink and it can't cool 100w without 300-400CFM going through it.

the heatsink has a better Qc than any waterblock of it's day, and the fan I have is a 110cfm 120mm silverstone case fan. Aside from that, i'm not only using this to cool the water, it'll be in line with a rad. The rad will dump most of the heat while the TEC dips it that much further.

Yeah well it never works quite the way you want it to...trust me. TECs dump a LOT of heat. I tried it once with an SI-128 SE with a 110CFM fan (probably the same fan you are using) and it literally cooked the base got so hot I couldn't touch it.

well all i know is with the way it's plated together now I can generate frost on the cold sink quite easily without even turning on the hot side fan. I'm not looking for it to do all the work, just help. I figure I already have it lying around, why not put it to good use. I don't wanna direct cool my CPU as I'd be afraid of screwing things up, ya know all that danger factor.

the heatsink i have was actually specifically designed for air cooling these TECs. It's used in commercial cooling units like water coolers.

Can we see this heat sink please? and there is little danger in sub ambient TEC cooling

Sure thing, here's the pictures I took when I was first testing. Note the frost on the third picture, and that's through two 1/8" aluminum plates, not exactly ideal. The last picture shows the voltage running the TEC and the temperature on the cold side after I attached the copper flower to the two layer cold plate. Just to reiterate, this heatsink itself is nickle plated copper.

as far as my concerns about directly cooling the cpu, I don't like the idea of what'd happen if something went wrong with the TEC and it reversed and dumped all that heat on the die, or simply cut off and suddenly there's no cooling at all. using it to chill water I have a little more peace of mind and backup.

aside from all that, this'll be simpler for me than trying to condensation proof my mother board. this will be my first water loop so simple is good.

That is one BIG heat sink .. where did you get it from ? i find it hard to believe it's copper

By the way a TEC is ridiculously reliable AND it WILL transfer heat even without power going to it ... anyway you can just setup thermal shut-down if something goes wrong

Anyway keep up the good work

Very interesting. That looks like a good setup, even though it's an air cooler. Got any links to where you got that heatsink?

I got it from the company Melcor back when their website was on yahoo. That site no longer exists (s'been 3-4yrs or more since I got it). Looking through their current site (www.melcor.com) it doesn't look like they that specific heatsink anymore, but they do have alot of other parts now like heatsinks, air-air chillers for putting the cold side in a sealed container, recirculating chillers, and even plates that have copper tubing running through it for chilling liquids in line (that last one is expensive though).

The main thing they make is the TECs themselves.
