push + pull = higher idle temp?

dunno · 11 Jan 2012 at 19:40

Had a 1850 GT fan pushing air through my True and idle was high 20s and load was low 60s. Decided to put 2 1450rpm GTs on the True in push+pull and am getting lower Load temps (5-6 degrees) but higher idle temps (+4-5 degrees).

Is this normal?!

I suspect it could be due to replacing one high cfm fan for two lower ones, static pressure will be lower as well on the 1450rpm fans.

But surely if I am getting lower load temps with 2 fans then the idle temp should be lower too? :confused:

I'm going to put the 1850rpm fan back on and compare, maybe I did something to the TIM when fiddling with the heatsink.

Different ambient temps?

Wouldn't worry about it, load temps are what counts...

agreed,
also is it quieter?

It is quieter, and the system temps are around the same. I'll leave them in push/pull for now and when I get time I'll see what 2 x 1850 fans can do with regard to noise and cooling.
