Mcw50t + X800pro

[[_Silence_]]

Anyone has an ideia on what temperatures should I have with MCW50T + 80Watt TEC with the radiator EVO120? (the WC setup is only for the X800PRO). Ambient temperature is arround 28ºC-30ºC.

Ati temp probe gives me like 2°c idle (1.75v and 610core 16pipes enabled) but gets to 40-50°c under heavy load. The 80w pelt isn't powerful enough to keep it cool. But it still beats normal h2o I guess.

I'm getting temps arround 25º IDLE and 43º Full Load, very stange. The TEC did ice without the graphics card, so its very strange.

your rad is probably not powerfull enough. the hotter the water the more effiecient works a radiator. good rads can dissipate heat even when the water temp is only slightly above ambient...

or its the fans... what fans are you using?

Dont know the brand, but its good enough i think.
Now i've added a second radiator, BIX, but the results are worse. Could it be the TEC dying?

hmmm could be... but i think if tecs die they just stop working.

what are your water temps?

if adding another rad makes the temps worse maybe the pump is too weak?
2 rads are pretty restrictive...

The pupm is Eheim 1046, got a 1048 somewhere, gotta test it.
Even with the Twinplex waterblock (no pelt), the diference between 1 or 2 rads is 1ºC better with 2 :S Might really be the pump.

[saaya]

the difference between one rad and two rads without a pelt is of course going to be much lower :P

without the pelt you have less than half the heat the loop has to handle :D

and yes, your pump is VERY weak. it has a theoretical max of 300L/hour ,the average people have and wich works out best is 1000-1200L/hour :)

Man I get way lower temps :cool:

At stock volts, I got -21 deg C idle IIRC (havent run stock volts in quite a while :p: )

At 1.8V I get h2o temp - 13 deg C idle, and h2o temp + 22 deg C full load. Obviously 1.80V is too much for that little 80 watter :p: , really need a 172W pelt for the higher voltages.
