Is it possible to undervolt an i5-650 from Windows?

My office PC has an Intel i5-650 stuffed inside a tiny little case and it's been overheating like crazy as of late (95c at maximum load).

I've installed ThrottleStop but there's no option to change the voltages anywhere. Neither there's an option in the BIOS to off-set Vcore voltage. The PC has an Intel DH55TC motherboard, FYI.

Any ideas?

Undervolt won't help, replace TIM under cooler.

I've replaced the thermal compound as well, but it didn't help much, probably because of the low-profile cooler it has. Plus, the case has very poor airflow with just one small intake fan.

Time to clean it maybe? . Frankly, undervolting won't help much, but you can always try with Intel Xtreme Tuning Utility.

I tried Intel XTU as well but it doesn't seem to support older processors. My only option appears to be ThrottleStop, but I just can't figure out how to change the voltage.

Some users have had success getting Throttlestop to undervolt the i5-650. Might give it a shot. https://www.techpowerup.com/download...-throttlestop/

Let it burn or increase air flow in the case. I had the same issue with a Dell Optiplex case, and I just gave up and bought a cheap $20 newegg case. Night and day difference in temps.

What users? Where?

Intel added voltage control to their 4th Gen Haswell CPUs. Voltage control did not exist before then. If there is no voltage control available in the bios then it is not possible to change the voltage on this computer.

Please tell me, you meant no voltage control for locked CPUs or non overclockable chipsets.
