Yet another Zalman thread...

post #1 of 6
Thread Starter 
I have the 7700CU cooler, and while I think it does a good job of cooling my 3.06 Northwood, (idles in the low 30's, up to about 42 under full load in testing) MBM (and Sisoft Sandra)only show the max RPM in the mid-1700's, where it's SUPPOSED to go to 2000 RPM's. I have their "Fan Mate" adjuster installed. Could that be causing the drop in RPM's or are the programs reading it wrong? If need be, I suppose I can do away with the controller, and let the motherboard control the fan speed. I don't have a problem if it's a bit noisy, since my 6 80mm case fans and 2 in the PSU sound like a 747 anyway.
Thanks.

Give it a try, more then Likely it is the Fan mate limiting the RPM's...

I found the same, and I think it's because the Fanmate 2 is rated upto a maximum of 11V and not 12V. I aatached my Zalman fan to the MB in the end, but as the Winbond PWM chip switches the fan off below 60C, I use Speedfan to maintain the speed at 100% (1950-2050 rpm), and it's not very noisy anyway at full tilt.

Not sure I'm happy with this heatskink after paying GB£35 for it!

Mine does a great job maintaining temps, so I'm happy with it in that respect, but I was concerned at the loss of RPM. It's gonna be a PITA to make this change, but I'll try it.

Maybe someone should notify Zalman. By the sounds of it tons of faulty products..maybe something was made incorrectly and require recalls?

I took the fan mate out and now the maximum RPMs are 1875.

I like my Zalman but I think I may replace for one of those with a Heat-Pipe design, like the Tuniq Tower 120.
