Waco Posted October 7, 2010 Posted October 7, 2010 Just a stupid question. The Coolermaster CFM 90 came with a 3 pin connector. Will it run faster/better if connected to a 4 pin connector or a 3 pin connector? I just checked, my card runs at 90 when the chassis fan is attached to the 4 pin connector (from my PSU) instead of the 3 pin connector on the motherboard! Otherwise, it will continue to rise above 90 steadily when connected to the 3 pin connector on the board! It's likely your motherboard has some sort of fan speed controls enabled in the BIOS to keep fan noise down - so the fan spins faster when plugged directly into your PSU. If you can stand the noise keep it plugged into the 4 pin molex adapter. Share this post Link to post Share on other sites More sharing options...
n0b0dy Posted October 11, 2010 Posted October 11, 2010 (edited) I would like to personally thank Waco, IVIYTH0S and gabrieltessin for taking out time to post in this thread. Although it may not seem so, but having somebody to reply to your queries, and just post a reply, is very very helpful, and goes a long way. Thank you. I have finished all my stability tests. I do not have screenshots, because these tests were conducted over a period of 2 days, and I simply forgot to compile all the test data into graphic images. However, I have notes, and I would like to share them with you.

I had to increase my CPU VTT voltage to get my RAM stable at 1.65 volts. Although Corsair TW3X4G1333C9A 2x2GB is rated at 1.5V, I read some posts where Corsair techsupport advised users to increase the voltage to 1.65. This RAM should be advertised at 1.65 volts. I did not run any benchmark tests because I wanted a stable system, and I think these tests are enough for now! If anybody has anything more to suggest so that I can make my PC more stable then do tell me. Thank you all once again. I will try to come over to overclockersclub.com whenever Im online. If I do not post, please do not take it as a sign of selfishness, and do respond to my queries in the future. Thank you all! God bless you! P.S. - I still haven't performed the OCCT Power Supply test! It's ironic, considering that was the thread topic!!! I won't be performing it anyways!

Waco Posted October 11, 2010 Posted October 11, 2010 Looks good! I would suggest lowering your PCI-Express bus speed back down to 100 MHz - there's no real gain for raising it and it can cause all kinds of problems that are hard to track down.

n0b0dy Posted October 12, 2010 Posted October 12, 2010 Done! Changed the PCI-E Frequency back to 100! Share this post Link to post Share on other sites More sharing options...
