Swiftech Thermoelectric Waterblock

post #1 of 28
Thread Starter 
Hey everyone,

My idea for my homemade chiller sort of died but I was searching around and I found this: http://www.crazypc.com/Merchant2/mer...t_Code=93048K8 . Now would this block just take the place of a normal waterblock in a watercooling loop? Say I had a custom Danger Den setup, would I just take out the DD waterblock and replace it with this Swiftech one. Obviously I would need to do some insulation but and my temps wouldnt be into the negatives but they would still be very much below ambient right?

OC newbie where are you

thats a tec. you need a different power supply and yes that would take the place of a normal waterblock and would give great temps

Yes i forgot to add that I know I would need another PSU...but that is pretty simple and seems like a great investment considering its only $40 more then the storm I was going to get for my setup...

p.s. Ares who/where did you get your FPMW from?

well its a sad story really. I was bidding on ebay and bid 200 bucks for one. Was willing to up to 260. I went to a b-day party forgeting when it ended and it ended 5 minutes before i got back home (1 am). The final price was 255

Now i'll have to do more searching on ebay...

That sucks...keep looking.

Anyways can someone give me a link to a suitable PSU that can power the block?

zerohour my appologies for not getting to you sooner.

As others have said, yes that Swiftech TEC/waterblock combo would go in place of a traditional waterblock. Condensation proofing is a must, you'll have to grease up your CPU socket and surround it with neoprene as well as the back of the motherboard.

As for a TEC power supply, most people go with a dedicated meanwell because it works very well. While it's possible to run the TEC off the PSU, most computer PSUs don't handle 26 amps sustained very well. Also most conventional computer PSUs require a bit of load balancing on all rails which means you'll have to hook up other things or bypass that with a simple resistor mod.

As for CPU temps, with a 226W TEC running at full load, sub zero temps while idle is possible. Your load temps will probably be above the 0C mark but definitely well below ambient. Keep in mind that you'll need a pretty hefty rad to keep the 226W TEC cool, what rad do you have or are you looking at right now?

Ok thanks for the help,

First off I do know about the condesation proofing as I was looking into a chiller earlier. Secondly, I am willing to get a dedicated PSU but I was just wondering if there was one that wasn't $120 because that is alot for just a small PSU. Third, those temps seem great and I am very seriously considering doing this. I was looking at a 77 dual heatercore but now I am wondering if it is enough to keep up with the block. Do you think it would be able to?

Thanks for your help!

Most people buy the meanwell because it works well but you don't have to spend a lot of money on a power supply. eBay usually has some pretty decent deals although there isn't anything of interest right now. I'll keep my eye open though, if I see one I'll pass it along.

If you are just cooling the TEC and processor I think the heatercore should be enough.
