8350 = inferno only with the stock AMD cooler. As I said above a 3rd party CPU cooler can be had for approx. $25 and will definitely calm those CPU temps.

As for the CPU voltage....by default the CPU voltage is set to auto in the BIOS.

It needs to be manually set, turbo needs to be turned off and the CPU fan control needs to be set to maximum.
But I would need a Speccy screenshot and the make and model of your computer case, before I could recommend anything.


It's still an inferno. A better heatsink is just going to vent it into the room more

Which is the whole idea of a better CPU cooler.

He doesnt want his room getting hot. undervolting produces less heat, which helps that.


CPU cooler would just make the room warmer if anything.

Answer to OPs question about undervolting.

Either the CPU or the room must be hotter. OP said his room was hot, not that he didn't want the room hotter.
If he keeps running his CPU at those temps, he gonna ...lose the CPU.

I'm happy with the undervolting so far, it would normally be at 50-52 :D

Here ya go...maybe this will make it clearer...










/e CPU-Z shows the CPU core voltage (what the voltage is set at, in the BIOS). Core Temp shows the VID ...explanation below.

Important part is: You must keep the CPU at or below a core temp of...62C. At the time this screenshot was taken, it was 70F in my room.


BIOS settings that pertain:

CPU voltage = 1.275
Turbo = Auto
CPU fan speed control = 100% or maximum or Disabled (w/e your BIOS calls it)

Your processor has a load line that is Mhz vs voltage that is programmed into the chip, For every frequency you processor can run at, a voltage is assigned. Higher frequencies require a higher voltage than lower frequencies. It is this voltage that is the VID, and it depends on the frequency the processor is running at. The Processor tells the Voltage Regulator on the Motherboard what voltage to run at.

When you choose an absolute Vcore for the processor to run at in BIOS, you throw away the VID and run it at what you specified and at full frequency.

When you choose offset mode for Vcore, the offset (+ or -) is relative to the programmed VID and hence follows the load line as you change frequency. In this mode you can use power savings to reduce the frequency that the processor runs when not under load, and Vcore will follow the load line for the voltage adjusted by the offset. You can't do this using an absolute value for Vcore.
