Default OCZ Vendetta 2 Fan speed percent?

Hi all,

I have a question about the fan speed of this cpu cooler.
What percent fan speed do you put the fan on in BIOS?
I put it on 95% cuz i was scared in the beginning, but the noisyness was driving me crazy so i turned it down to 55% Is this safe?
It is being used on q9550 at 3.8GHZ (vcore at 1.36250) and I havent seen the temps go above 63 on 55% fan speed. I am using that clock 24/7. Would be safe to even turn the fan lower.. like 30%?

Thanks.

s288.

The only thing you can really do is try it and see. You're computer isn't going to suddenly explode if temperatures briefly go over 70-75 degrees, so give it a trial run and see how much fan speed you need. But if I had to guess, I wouldn't be surprised to see temps in the 70's - there's liable to be a fair difference is performance between 30% and 55%, when it comes to pushing air through a heatsink.

Get a fan like noctua or Yateloon and put it on the vendetta, that what I have done. The stuck fan suck alot IMO. After doing this I let the mobo does everything with a Q9550 at 3.8. it can go up to 1350 RPM with nothing loud and I have never see a temp over 60. Som this is the way I recomend. Or, try to set you fan at 30% and see if any temp is going over 65, if yes...downclock CPU or increase fan speed. sorry dude.

I don't know about your 780I board, I am not a pretty big fan of EVGA board...well not a big fan of any Nvidia based board...So I don't know. In my board there is a auto and manual setting and there is also a software that come with it but I think you should ask that in the Cpu's and mobo thread. Ask me if you need any more advice regarding to this thread I already look up with the same problem so I know how you feel and I think I can help.

The stock fan on my Vendetta 2 tops out at around 2000RPM according to the BIOS (no fan control enabled), and it's pretty quiet.

First of all, the fan coming with the VT2 is a 800-1500 RPM so I really doubt it run around 2000 RPM. Your bios should have a little trouble with CPU fan controll speed and run it lower then it is supose to do. I can show you a picture of a CPU at-0.5 celcius with a 65 000 RPM fan ( intel stock ) ???lol???

Second. Noise is according to everybody state of tolerence. My is about zero :) After installing many VT2 I know how their fan are running and for me they are loud.

I have another advise for the OP of the thread to see about the fan speed and temps.
Try these.
DealExtreme: $4.29 Smart Cooling Fan Speed Controller + RPM Alarm for PC (4-PIN Connector Allows Software Control)

You can plug you VT2 fan in it and in PSU ( with the proper adaptor ) and see what speed and noise + temp you like. If you have no way to let the pc controll fan speed in bios like in your previous post it could be a good way to do.
