Hi, I'm fairly new to adding components to my computer so my understanding is probably low to moderate.
I recently replaced my Glaciator fansink on my 8800GT with a Zalman vf 1000. Everything went fine with the installation (to my knowledge). However, the fan, which the Zalman spec sheet say is capable of reaching 2500rpm, is capped at 1700rpm. The fan (80mm) is plugged directly into Chasis_fan 2 on the motherboard. The cooler also came with a Fan Mate 2 fan controller - the fan plugs into that device and then back into the motherboard. The device is supposed to be a manual fan controller, turning the knob in either direction increases or decreases the fan's rpm. When I turn the knob, the rpm of the fan stays the same - the only noticeable difference is that the LED will flicker and change intensity somewhat. While using the device my fan caps at 1400rpm. I've checked my BIOS and there does't appear to be an option to let me change the voltage. I've also spoken to Intel support to see if the motherboard was affecting the voltage allowed to the fan, but she said they were completely unrelated and I should speak with Zalman. I haven't been able to get a hold of anyone over there, so I was hoping I could get some help here.
My setup is currently:
- Intel Core 2 Duo CPU E8400
- Microsoft Windows XP Professional
- Intel Desktop Motherboard DG31PR
- 4 GB DDR2
- Asus EN8800GT TOP w/ Glaciator fansink
- I believe all my drivers are up to date as of May 20, 2009.
Sorry, hit submit by mistake. Here is the completed version of my situation. If you need any more information, I'll try and provide it.
The fan only has a 3-pin connector that only seems to fit into the motherboard fan header and/or the fanmate2.
My power supply is 350w, but I have no idea how much strain it's under.
The instructions make no mention of any switches or wiring setups (other than the one I have already mentioned). It says rpm is only adjusted by turning the knob. I've tried pressing the knob in/pulling it out, but it's pretty sturdy and has no effect.
