A question on cooling

  STEVE71163 15:43 24 May 2003

I have just fitted a case fan blowing in from the front bottom part of my case today and it has made no difference at all??? I also have an exhaust fan at the back near the cpu which when i fitted that it took about 4c off. What could i have done wrong?

Many thanks for any replies!

Check the airflow - IDE cables may be in the way for example.

I have 2 front-mounted fans and with both of them on FULL BLAST (noisy!) they only knock about 2C off the CPU temp, but 5 off Mobo temp.

Their main function is to cool the hard drive(s) not the CPU.

Thanks MartinT-B. I just thought it would knock about another 4c but i was obviously wrong.

If you want lower CPU you need to change CPU heatsink and/or fan.

I have just turned my front fans to minimum (can't turn them off without unplugging from Molex) to check what CPU temp goes up to after an hour - atm it's 38C and Mobo is 18C

Will post back in an hour or so.

Thanks. I just took the side off my case and the graphics card fan is not turning. Does this only come on at a certain temperature?

My graphics card fan is not turning either. In fact it doesn't even have a fan!

some do, and some don't according to the nVidia site.

Problem is that their tech support FAQ is very paltry.

Thank goodness for that, thought for a mo that mine had flown away! :o)
