f8sn-c1 fan rpm detection??

I've been running Folding@Home intermittently and wanted to find out what the fan rpms were at to see if getting an external laptop cooling fan would keep the rpms down and not wear out the internal fans. I haven't been able to find a program that would display the rpms. At best I can get the cpu and core temps , GPU and HD temps using Everest and Speedfan.

Under normal operation of 5-10% CPU, the cpu temps are 46C/115F. with only one core running @ 100% temps go up to 56C/131F. Boths cores @ 100% brings the temp to 62C/144F. Interestingly, running F@H on both cores for hours does not heat up the keypad or the bottom either. The only way I can tell is the increased fan noise and warm air coming out of the exhaust port on the right side.

Any ideas for programs that can display fan rpms as well to determine how well the cooling pad is helping out the internal fans?

 

Asus NBProbe. However, using fan rpm tells you little about a cooling pad's effectiveness -- the change in system temp under load is a much better variable.

To my experience, Asus generally doesn't generally use more than 2 rpm presets, and then keeps a third in reserve if the system temps really spike. Using a cooling pad will likely only drop system temps on new notebooks less than 10C (more likely <5C), it's just not an efficient solution - you're better off undervolting the cpu if you're running things at 100% load a lot of the time... that will probably have a much bigger impact on temps than an external cooler ( see here for example).

 

NB Probe only tells me if the fan speed is normal, nothing about the actual RPM. Using that undervolt guide, I'm using rmclock to bring the voltage down to 1.0875 from 1.25. 1.07V lasted for 5 mins and then BSOD. CPU temps have dropped 7 C. So far F@H is running steady for the last 30 mins. we'll see if it holds overnight.

thanks for the info.
