Adjusting the RPM ratio between the pump and fans

post #1 of 3
Thread Starter 
Has anyone experimented with this idea?

My rig is in my semi, this means that my ambient temps range from 28 C to 35 C when the sun is shining. I started messing with the ratio and was able to bring my avg temps down 4 - 5 degrees C while under a full load.

Settings used to get this are:
Pump running @ 50%
Fans running @ 80%

My 3770k is clocked to 4.7 and I was encoding a file with handbrake. Temps went from 65 - 66 C running FanXpert turbo down to 61 - 62 C running the modified settings.

Any comments or ideas would be extremely welcomed.

we need more info as to what your water cooling gear is. and what speeds were you running before you started adjusting?

Its the Glacer 240L stock, set as exhaust. Fan Xpert turbo would set both the pump and the fans at 62% with a target of 55 C. That would have my pump at 1820rpm and the fans at 1488rpm. My thinking was that I should treat the system as if it were controlled by a thermostat, slowing the water flow while speeding up the airflow, and that seemed to work.
