What is "PWM" temp for Lanparty nF4 Ultra-D?

post #1 of 13
Thread Starter 
I'm just getting started learning about overclocking, and I downloaded SpeedFan to check my stock temperatures. I used a code from Speedfan's website to identify the temperatures for my DFI Lanparty nF4 Ultra-D, and it lists four temps: CPU (39C), PWM (54C), nForce4 (49C), HD0 (48C). I know what these all represent except PWM. The default settings have it giving me a warning at any temp above 50C (which of course it now is).

Can anyone tell me what this temperature refers to, and if indeed it is a problem that it is reporting at 54C? Once again, I am NOT overclocking yet. Everything is running at stock speeds.

The mosfets on your board, tiny chips around your cpu/ram area that control voltages.

Those PWMs can run at over 100C so youre fine.
Very nice!

True, but if you want a semi stable OC, or are pushing your OC to the limit, get some MOSFET heatsinks (assuming you don't have any) or mount an 80mm Fan over the sinks, to give you the best results.

BTW: welcome to oc.net!

If i remember my ultra-d it does comes with mosfet heatsink

Thanks for the welcome. :-) I have two further questions. First, what should I look for in finding the MOSFET on the mobo? There is a heatsink/fan besides the CPU one on the mobo but I'm fairly sure it is only northbridge. Second, what temperatures would you then recommend for a stable overclock, if not up to 100?

Your mosfets are located around the CPU socket (usually on left side) but in this case, they are covered up in little heatsinks as Shortfuse said. Just keep it below 70 and your fine, anything above that, were talking instability issues with OCing.

Most boards designed for OCing will come with mosfet cooling. The DFI's do and my board has huge heatsinks on all of them aswell.

You may need to increase airflow in your case, those temps are okay now but when you start upping voltages the northbridge and the mosfets will rise in temp quickly. See if you can get a fan or two blowing right on the board or just genereally inprove case airflow.
