Undervolting i3-4160

Ok so I'm undervolting an i3 4160 and so far i achieved -0.1v on the vcore with no bsod crash so far. About a stability test I'm kinda afraid to push this cpu with prime95 with the stock cooler since the temps reach around 80 degrees which is too high for a cpu. In normal idle state it sits between 30-40 degrees and max 65 under load in gaming and stuff like that.

 

Has anyone else here undervolted these cpus ? If so share your experience and i would like to know how far can i undervolt this chip with no underclocking.

If you want to check temps without pushing your CPU too hard, I recommend Intel XTU

 

It's very realistic and doesn't do anything crazy :)

Why are you undervolting it in the first place? It's not like it uses much power anyway

Not to save power, but to reduce temperatures. Voltage is probably the biggest heat factor.

Exactly why I'm doing this in the first place and that also means the fans will spin in less RPM which will result in an even quieter system.

 

The only downside to it is stability but when you sort that out the benefits are great.

 

 

I'm noticing almost no difference in idle temps but in load temps it's 5-8 degrees.

Bruh its an i3 it would produce like no heat, get a 212 or something

Is the cooler mounted correctly and the thermal paste good? Because not even my i5 4440 reached those temps with its stock cooler (Prime 95 was the exception). In fact, its been at full load for the last week 24/7 and its staying around the 700C mark.

The cooler is mounted correctly and the thermal paste is the stock that comes with the cooler , anyway it's been a while since then and the cpu hit max 67 degrees under full load with -0.1v undervolted. I also forgot to mention that the fan has a custom fan curve so these temps are normal.

 

Earlier i was tweaking it a little and the first bsod i got was -0.15v. Now running at -0.125v. Running some stress tests with Intel XTU , let's see how it is in real world usage.
