CPU overheats? Temp3 reaches 100 degrees Celsius and above

Last response: in CPUs

My computer frequently shuts down when it has a high load, such as playing games, watching videos while converting using Any Video Converter, etc. Using SpeedFan 4.49 I found out that at startup, Temp3 plays at around 65-75C. Once I open Google Chrome, it goes up to 80-87C. And when it reaches 100-105C, it shuts down?

I've already tried using the computer with the case open but to no effect. It has no front case fan but it does have one on the side and one at the rear end below the power supply fan.

My motherboard is an ECS G31T-M7 (link here: http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail...), and my CPU is a Pentium D 930, which as it turns out is not supported by the motherboard. I'm mentioning this because maybe this is the reason why it overheats? I'm not entirely sure.

Any help would be appreciated.

If the motherboard didn't support the cpu, it wouldn't even boot. What cpu cooler are you using? You might need to re-seat the cooler and/or replace the thermal grease.

+1 both CPU and mobo are LGA775 so they're compatible. I suspect the thermal grease/cooling as well.

I'm not actually sure what my CPU cooler is? How do you determine it? And if that's the case then maybe my CPU is supported after all. I assumed otherwise since it wasn't listed on the list of supported CPUs.

I'm going to assume you have a stock cooler on the CPU - especially because I can't imagine anyone would invest in an aftermarket cooler for a Pentium D!!!! My word that thing is old lol. This is a video on properly seating your CPU https://www.youtube.com/watch?v=8emxPAZZ53w and this is a video on how to properly apply new thermal paste https://www.youtube.com/watch?v=0eC3Ni7Sshw you can start at about the 10 minute mark. Use isopropyl 99% alcohol and a qtip to clean off the old thermal. Then follow the "pea method" to reapply and reseat your heatsink. Not that hard a task, but if you have ANY questions, just ask.

If you're not sure, then it's most likely the stock cooler that came with the cpu, which would be several years old now, so the thermal grease could easily need replacement by now. If someone else built the computer for you, try asking that person. Otherwise, open the case and take a photo, and I can try to identify it.

Pentium D? Wow that's some old school tech right there. Net burst was known to run very hot

Maybe if building now, one wouldn't, but I did back in 2007-08 - I had a Pentium D 820, and I think first I tried to use a Cooler Master Hyper TX2, then later a Zalman Reserator 1 V2, although I did bad jobs of installing them - one of the push-pins of the TX2 popped out after a few days, and a hose popped off of the cpu block of the Reserator kit while I was away :(

Is there maybe a different problem and not the heatsink? It's just that I'm afraid I might accidentally damage my CPU.

It appears that it is the stock since I searched for it on Google and its the one I have.

Well until I graduate and get a job, this is the best computer I'm gonna have. :)

UPDATE: I just replaced the thermal paste and now the temperature is 50-60C on startup and 70-80C once Chrome is opened. Thanks guys. I'll test if it still overheats when playing games.

Good to hear. Don't forget to select the solution to your problem. Good luck!

Quick question guys. Before reapplying the thermal paste the fan speed of Fan2 used to play around 2000 or 3000 rpm, I can't remember which one. But now, its only about 1800 rpm. I know, this has nothing to do with the thread title but still, any ideas?


UPDATE: Turns out that after a few minutes of use, the temperature returns to its previous pre-reapplying of thermal paste state.

My initial thought is just to get a new heatsink/fan. That would certainly cool things down more than a stock cooler. However, it sounds like you have more of a problem than that, so a new cooler may only mask the real issue.

Is your voltage too high? Frankly I don't know of a cause other than inadequate airflow, insufficient heatsink/fan, too high a voltage, too high an overclock... Am I missing anything? Those are the main causes, anyway. If you had an extra 20-30 bucks I'd get a new heatsink/fan, but how long do you plan on using that machine? I mean... it's so old lol

Well Vcore1 is 1.26V and Vcore2 is 2.16V. It seems low. I'll be getting a new PC in about a year at the least. I'm still in college, I don't have cash to pay for spare parts.

2.16V is wayyyyy high if that's your CPU voltage... at least I think it would be, let me research these old Pentium Ds...Yea, nothing special about those CPUs so 2.16 is way too high. I'm not certain that's your core voltage, though. 1.26 is perfect and I assume that's your core voltage, so that's straight. Curious where that 2.16 comes from, anyone? Too high for memory, too.

You can also try and clean your stock heatsink fan by blowing compressed air to get rid of the dust that could be accumulated over the years. It would bring down the temps also since you already reapplied the thermal paste.
