Here's help for people who want to make their system run cooler for free. I found this undervolting guide made for laptops a month ago and I have successfully undervolted two processors: my desktop computer's (made of laptop parts) and my mom's laptop's.

I think the undervolting should work pretty much the same way with normal desktops but I'm not sure if you will be able to tick/untick the lower multipliers. I managed to drop my desktop's processor max temperature from 81c -> 70c and I was also able to tick SuperLFM on which cuts processor's FSB to half when idle, resulting an idle temperature of 36 celsius. I noticed my GPU Core's max temperature drop about 5c too when I undervolted the processor. This could be due to the tight casing.

Here are the advantages and cons about undervolting that are also listed in the guide:

+ Cooler CPU (5 to 20c cooler)
+ More battery life (15-30mins more)
+ Less Fan noise & activity
+ Longer overall notebook life
+ Eco-Friendly

- BSOD (Blue Screen of Death)
- Takes a lot of time but you don't have to do it all at once

I also want to add that there's no performance loss at all. Just make sure your system stays stable.

Read the instructions carefully, it won't take a rocket scientist to accomplish. You can ask me if you need more information. Happy undervolting!

OR u OVERvolt ur hardware, overclock it with like 20 percent, so u can do ur work quicker (cuz the system is faster).
Then u will also win batterypower cuz u dont need it to be on for that long


edit: oh crap, with higher voltage the power drains quicker ofc. im so stupid sometimes. Almost had a eureka moment right there. damn weed blebleble

lol of the day, Anus.

Talking about overclocking if you plan to overclock your processor, it's easier to first overclock it and then undervolt it (if still possible)

Less voltage => Less stable

nice one jesa, sticky this topic!

Haapis, your system won't become unstable before you go under a certain voltage limit which is unique to every processor. The default voltage set in the factory is usually high just to make sure every processor of the same model is stable. This is why you can undervolt it in most cases without going unstable instantly.

Yep that's totally true.
For a laptop it's a pretty good mod.
I don't really care about my desktop though, can't run out of power anyways
