Replies: 6

A 45 nm CPU will run cooler than a 65 nm or 90 nm processor when both are running at the same speed. Not necessarily true. A larger die size, whatever the process resolution, can allow the more accurate build of the transistors which often results in more power efficient transistors and therefore l...

I have a old Antec P180 spcr_edition case. I started with a home made blank cover made from a VHS case. I mounted the cover on the inside on the fan mountings as "syee" has done. It made a big difference. But, I had weird resonances at the top of the case and so now I use a HEAVY book.

Kilgore said "What are you using for case fans?".

All 3 fans, 2 case fans and the CPU fan, are the Gelid Silent 12 PWM model and are connected to the CPU fan header with PWM y-adapters.

" the Q9550 doesn't downshift when idle" I thought that the Q9550 down shifts from 2.83 GHz (8.5 x 333MHZ) and 1.25 volts to 2 GHZ (6 x 333 MHz) and 1.1 volts when at idle. Generally you will get a bigger energy savings, and therefore noise reduction opportunity, by using IGP instead of an add-in vi...

The top of my p180 case resonates without the top fan running. I screen fans for vibration by placing them on a surface that will amplify the vibrations and then run them at a full 12 volts. You didn't say and so I am supposing that "I have the fans set to low" means you are using the Antec TriCool ...

What I used to do: The rectifier diode adapter works well. I use a Zalman Fanmate ( $CAN 10) to determine the fan-rpm-airflow combo that does the job and then measure the voltage that the Fanmate is delivering to the fan. Then I build an adapter with the required number of diodes to get the voltage ...

In my experience a 60x60x25mm fan has blades 3x wider than the usual 60x60x10mm fan and blows 3x the air for the same rpm.

I doubt you would regret upgrading to a new HSF with a larger fan. Perhaps something like this:
