Motherboard Fan Voltages

I just posted this article for discussion:

Motherboard Fan Header Voltage Variations (http://www.overclockers.com/tips662/)

well a delta on the MSI K7T Turbo runs at 5500RPM on the motherboard, 7600 when on the psu.

man, 7600 has to be hard on the ears!


Good article JoeC :)

I've written an article about cooler overvolting, and sent it to Joe... :)

Anyway, I've overvolted more than 10 coolers till today... And, only one had a sensor (others were oldies!)... :)) I've measured the rpm, and, the results were very good!

Cooler was copper orb (I think, anyway, some Titan sh*t), rotating at 5000rpm... And, overvolted it rotated at 7500rpm!

Overvolted to 24V... I didn't test it at 17V, but could be around 6000rpm...

Now, I think I'll write an article about DC brushless motors, so people don't think they can burn cooler just by overvolting it! :))

But, I'll need some time, now are exams, and nothing could be done till the end of February... :(

Anyway, I'll do my best to write this article on english... :) It'll be pretty hard, but I'll give it a try... :)

See you guys!

I found some interesting results like you had suggested. My buddies dual athlon system runs cooler under load due to the increased voltage of the 12v rail. I thought something was wrong with the temp sensors at first but then I tried 2 different sensors and found this to be true.
