Just realised something else that minimize condensation... If I have airflow over that area... it lowers the rate at which condensation occurs is this correct???

Just like moving water is less likely to freeze... lol, or am I totally wrong...

edit: hehehe, got bored, and realised i HADN'T YET done this - MAKING ICE

g0t ICE????



imma go have breakfast... while the ice melts... ehhe (that's why i got the sponge there)...

Never heard of RTV sealant.
Is that better than dilectric grease?

Your setup looks interesting groovetek, but i'm surprised you're actually getting any lower temps with the pelt running @ 90w.

My old 3400+ @ 2.72GHz with 1.7v through it put out over 130w of heat.
Could just be a .13 thing though

um, i don't know... i bought rtv sealant AND di-eletric grease... the RTV is mainly to seal gaps... the dilectric to cover pins and mobo components and stuff....

here are some more pics (my new block insulation - works a charm):






edit: wtfomgbbqzors... didn't realise i had left the molex unplugged til looking at that pic, rofl.. FFS... clearly it's not an important one... ahah, since i've been stresstesting it with no problem...

edit2: i've got that piece of paper under the block just in case something starts dripping... not a single drop of water yet tho... and i've given my case a couple gentle knocks just to make sure, so far so good...

i CAN however, see very very slight condensation on the nuts that are holding down the neoprene to the copper plate (ie, the ones pictured above). not much of an issue I guess... still... it's a computer after all, and any water won't mix well.

yeah about the wattage thing, thanks for that, i'd say the 90nm would be a fair bit less... once i get the 24V PSU the Qmax ought to be close to doubled and with a larger deltaT, since it is doubling the voltage. so, hopefully it can tolerate my cpu at beyond 3ghz... cos at the moment it cannot.

edit3: i just did 2 1M runs, and got 28.360... that's surprisingly quick - considering my mega tweaked optimized, non-app-flooded win xp sp2 install back when i did the 1M runs on the superpimod challenge thread i scored 28.218...

this windows has everythign installed, lots of things at startup, network connection enabled/connected, not a fresh bootup, wallpaper and visual effects and what have you all turned on... and i get a time likethat?!?!?

if i ran it another few times it might even break 28.3s...

very nice groovetec.
one think you will need looking if going to the 226w pel and full 172w is that the radiator is going to struggle.

I was wondering about that too actually, a single 120mm rad isn't going to be much to cool down the 172w of heat generated by that peltier.
