 Post subject: Zalman 7700 RPM's boost?
PostPosted: Sun Aug 07, 2005 5:42 pm 
Hey guys. i have the zalman 7700 120mm HSF ....(wonderful fan, awesome job zalman!) and i was wondering if there was anyway to get a speed boost out of it like grounding it to anything....the max i can run it is 1800 rpm's on the standard 3pin connector on the mobo....is there anyway to boost this? i know i have plenty of PSU for it..so any advise would be most appreciated! thanks guys!

btw speed fan and the bios say it's at 100%

Don't even try. You'll have to increase the voltage to do it, but the bearings in the fan are designed for the fan's max (in this case 1800RPM). If you start to consistently go over it and hold it, the bearings will start to shred then you're out a fan.

:mb_iagree::

But if you do decide to do it, please video record it with sound so we can all watch your HSF blow and shortly after your compuiter..

I have a Zalman 7000 and I have TAC type case (a drilled the hole and made the duct system myself) with a 120 pushing air right at it. It raises my RPM's on my Zalman 200-300 past max. Its been ok for the last year this way, and my temps on my 2.8c never get past 45c even when overclocked to 3.5. So far no problems with the bearings but I keep a close eye on my fans and temps with auto shutdown set at 62c.

Works for me, but anything like this involves some risk.
