Ph II 555 + low volts + hyper 212+ = amazing temps!!

post #1 of 17
Thread Starter 
I recently go fed up of overclocking my 555 so i decided to go the other way...undervolting the thing, well, I got it stable at stock speeds (3.2ghz) with a mere 1.15v

Now temps were never a problem for me with the hyper 212+ but now its just ridiculous, the room is 33c case temp according to my NZXT sentry LX is 36c.

Now get this the cpu is idling at 22c and at full load its at 27.5c IN A 33c room..i'm literally boiling in here and this chip is cooler than I am.

The next step is to overclock at these low volts and see if it is possible. I'll keep you guys informed.

BTW i did not start this thread to brag but i was looking for a undervolting thread about the 555 and i could not find it so all my findings here will be for all the 555 owners out there.

Sadly, the Chip's not actually that cool, on air or watercooling, its impossible to cool below the temperature of the air passing threw the cooler. Your CPU's just giving you incorrect readings.

On a better side though, you'l probably be able to run your CPU passively (without a fan) with that voltage quite easily, so you can have a nice quiet system. smile.gif

You CANNOT have temps lower than ambient with standard air or water cooling. You simply CANNOT.

Are you reading CORE temps or socket temps?

Physically impossible. Mother nature won't let you do that.

If they are core temps, they might be slightly offset (i.e. ~10 degrees on phenom II x6) below actual temperature. Even then, that is a very good result, assuming 10C offset you are only 4.5C above ambient! thumb.gif

I've read them correct... core 0 and 1 were around 21c and the TMPIN0 in hwmonitor reads 28c (which i assume is the cpu temp) cause thats the only other one that rises under load...but here is a pic of the HWmonitor...I just state what i see. It's late evening now and the temp is around 28c

TMPIN0 is the only temp that matters, depending on where the sensors are for your case reading - the air going through the HSF may be cooler.
