repeat with the 7770 rig. measure the room temp from the INTAKE fans of your case. NOT exhaust.

there is no way in hell that the 7770 will heat the room up faster than a 480.

you probably think that the 7770 heats the room faster is because the exhaust temp is higher and the heat is more concentrated to where the PC is located. and in the case of the 480, the exhaust temperature is lower and thus it will not make a concentrated heat pool.

I believe this is the real answer.


After further testing, it seems this is the case, the 480 machine is much more bearable even though it outputs more heat.

Neither card is a 400w TDP, although that may be the recommended minimum power supply. Means nothing about how much power the card draws or how much each core dissipates as heat though.

The GTX 480 with the OC i have on it, does use close to 400 watts.

Pushing 890mhz with 1135mv from a stock 700mhz with 1024mv.

How are you checking? I find it highly unlikely that something that pulls only 250 watts at stock would jump another 150w from a small increase in voltage and core speed.

That is a huge overclock for Fermi on air... and that is massive volts for Fermi also.
