CPU and Fan Speed help

[sapilingmo155]

Just bought a Phenom II 965BE, but then when I tested it at the first time, the fan speed goes
at 5800+ RPM and CPU temp is 39C.. Is it normal?

Any suggestions? I think its not normal cause the fan makes noise and very fast..

The temp is good, but the fan shouldn't be spinning that fast. Faulty HSF?

 

[sapilingmo155]

what's that?

HSF = Heat Sink Fan. In other words, the fan on top of the CPU heatsink.

How are you determining the speed it's going at? Through the BIOS? In Windows, download Speedfan and run it...might give a better idea of what speed it's going at. 5600rpm seems a bit outside the capability of a stock fan to me...not sure if any PC fans go at that speed, actually! I'm guessing it's an erroneous reading.

The temperatures seem fine. Is the cooler you're using the one that came with the CPU?

wouldnt think any fan other than a 50mm or 60mm would spin that fast

if it is you would know about it from the jet engine sound coming from your pc

look in the bios for cool and quiet or something similar and enable it

Basically you need to boot into the BIOS and enable the Auto Fan Controlling features.
My Phenom used to start up like that and then after setting the CPU fan to PWM and enabling the threshold temps to 55C everything is fine now.
Set the minimum Fan speed to 20% and enable 100% Fan control.
It actually all depends on the Board, but this is the way the BIOS setting are available on an MSI board. Asus also has the same features but the language is slightly different.

just don't know the abbreviation for the heat sink fan (well thanks for answering that hsf ).

Yes, been using the one that's on the package of the CPU. I didn't install yet an OS so I'm seeing the data through the BIOS.

I'd not worry just yet, then. Check you've got the fan connected to the correct header on the motherboard (should be connected to the one labeled CPU_FAN) and as long as your temps are within the 40 - 50 deg C mark in BIOS, go ahead and install your OS. You can check the fan speed from there.

I noticed also, after testing it for several minutes, the CPU heats fast.. BTW my board is biostar.

 

[mcnumpty23]

its normal for the cpu to run a bit hot in the bios--once you get into windows you should hopefully see a difference

if not then check the heatsink is on ok

 

[sapilingmo155]

Ok. will Install an OS and give my feedback ASAP.

 

[sapilingmo155]

thanks for all your help.. its working now with a normal RPM.

you are welcome 😀
