Need help on MCW50-T

[htkm1]

Gonna get a MCW50-T soon. First here is my W/C set up.
- Intel mobo
- Radeon 9800 pro
- Cascade WB
- MCW50-T (soon)
- Thermochill 120.3 Rad (I think my Rad should be able to handle the cpu and the TEC right?)
Using two PSUs. Antec TP 480W to run my system and a cheap 300W running my 3 x 120mm Delta fans for the Rad. Now the TEC is a 80W pelt. so if I were to run it with the cheap PSU would it be ok? Or do I need to get a good quality PSU. :(
Regarding condensation, do I need to protect the mobo also? Like insulation round AGP slot area, Put dielectric grease into the AGP slot? Cause Swiftech's MCW50-T kit only has protection for the Graphic card.

Your advice and suggestion appreciated. :)

Most power supplies should have enough amps to power a measly 80w tec. You might want to check the amp rating on the power supply first though.

You should be alright with that PS, you need to put a load on the 5v though. Run a HD off of it or something also.

You shouldnt need the dielectric grease, i have one and have not had any condensation problems in a year. But if you want it couldnt hurt.

You need as much insultion as possible. My card almost burned because I believed ppl saying that for MCW50-T insulating is not really necessary, not to mention dielectric grease!

GPU side is not a problem. YOu may want to add some more neoprene around supplied block/insulation assy to bet better temps.
Back side is a real danger thou. Use some methylated spirit (or any evporating non-residue alcohol cleaner) to clean back of your card. Then get yourself the ehickest and the biggest piece of neoprene which will fit on the back of your card. I used what was left from MCW5000-T assy. Use double sided tape unless you have neoprene with slef-adhesive backing :) to stick it to the back of your card. Make sure it is glued as much as possible. NOW cover any meeting lines of neoprene and PCB with dielectric grease (same for GPU side) to prevent air from getting inbetween PCB and neoprene when it comes off in places after some time (it will no matter what).
The only alternative is use of some DIY mechanical clamping system to hold insulation pressed to your PCB.

The more you insulate the better temps you'll achieve. TEC cooling is sub-ambient cooling solution and therefore one would want to cool only what one wants, not air aroud your card :)

In case of PSUs beint capable of running your pelt... Yes, check 12v line SUSTAINED Amperage rating. As far as 5v line loading... I've been running my 300w Chieftec PSU with MCW50-T hooked to it's 12v line and plenty of 12v fans without any 5v line loading for alround 6 months and it's fine...
