Testing Undervolt TEC Air cooled - Page 2

you're right, after all the BT alone might have the same if not better performance. But like I said in the first post, I just wanna play around with the TEC cuz I have so many unused part laying around plus I dont have to worry about the light bill (it's free) so I'm not worry about how much power consumption it's gonna take. Everything still have to wait untill I put it on my P5WD2-E Premeium cuz right now the limit to my OC is the temp. I'm @ 4.48ghz & load temp is like 69 C on the BT+Silverstone 121FM, both CPU & HSF lapped.

Nice! Most people try for that on water xD

What heatsink and fan is that? Those aren't bad temps for only 5v. Believe me, your power bill wouldn't go up running that, it's probably only drawing like 35 watts... How hot does the heatsink get? After running with the peltier on, load the CPU up for a while and fell the heatsink. If it's not warm, you should try upping the voltage to the peltier a bit. If it is warm, you need a stronger fan or better heatsink.

If you have two spare PSU's that you're not using you should try building Engineer's "more complicated" PSU. If you're lucky enough to have two PSU's with adjustable rails, you'd have decent voltage controll from about 6.5 to 12 volts. Perfect for experimenting on that air-cooled TEC.

I'm not sure what kind of HS I got since I took it from a Vaio rig. It looks kinda like the SilverStone SST-NT01-V2 but it has 5 heat pipes & using the 120mm fan instead. The temp on the TEC hot side when it's on is still very cool.I can touch the base as long as I want. I think it would be perfect to run it at 7 volts. I'm gonna try to built the PSU that you suggested. Thank you for your idea.

Same setup, but this time is 6 volts for the TEC. Idle drop 1 C, load drop 3 C. Will try 7 volts when I have time to get all my tools. TEC still very cool.

The thing is I dont want to deal with the condensation. All I want is to keep my load temp around 40 - 50 C and I'll be happy.

Then just get a BigTyphoon and get one with it...lol. Theydon't use massive amounts of power....

nice, I have been thinking about using a TEC with my water cooling rig, but I think I would have to setup two different loops cause my one loops is doing my cpu and my graphics. and I think the tec would put to much heat into the loop.

The BT couldn't keep my 920 cool enough @ 4.48 and I know I can go a little further if I have better cooling.WC is not my option right now that's why I decided to play with the TEC.

I've been watching these threads and have ordered some TECs and stuff. I'll be going the air cooled route and I think I have figured a way to run the TECs on 12v and keep them powered up.

Coolers im using:
CPU: Thermaltake Blue Orb II on top of a 95watt TEC
GPU: Zalman zf900cu on top of another 95watt TEC

My main goal is a system that is more portable than most of these monstous rigs with water cooling and 5 PSUs. Im also using all ATX power

let's see if the BT can beat this idle temp

updated with new pics of the psu i've just completed. ( ~6.7 volts )
