What is overheating

Trojan Horse · 27 Apr 2016 at 21:44

I have a fan controlled and set my fans to low. I can't hear it but temps rise. When the OS first loads it goes up to 60-70c then idles at 40c with fan spinning on minimum. However, sometimes, these temps cause BSOD/random restarts.

I've figured it's due to temperate, as fans moving at 100% don't cause it. I've reached 60/70c on CPU before without crash on max fans, so why do I restart now just because fans are on low?

Have you actually used an application to monitor your temperatures to see what else might be getting hot?

Yeah. I can even run OCCT PSU tester, with low fans, heat up at 60-70 and let it stay there. It's only on startup that it crashes if my fans are low. A PSU issue?

You are hitting the so called Tjunction Max is what intel call it.

What is overheating ? Really go figure.

Your cpu is over heating it will either throttle back or shut down to save its arse and you a chunk of change.

Idle is you are doing sod all so cpu lowers clocks, once you start playing a game or encoding etc it ramps up to max speed and increases temps on cpu.

Most CPUs do 70-80c but after that depending on CPU it can crash or throttle back, as in to lower required CPU speed.

Check thermal paste and cpu is seated correctly. Get rid of dust and bum fluff from CPU radiator.

"what is overheating" "what part of my system is specfically the product responsible for my over heating"

my fans max once i do something properly. right now i don't even have a gpu installed.

i cannot be hitting the tjunction max at 70c. please read.

How do you know your BSODS are temperature related and not just pot luck they happened when your fans were set to low? What are the BSODS?

What application are you using to check your temperatures? Can you paste a screen shot so we can see the other temps on your PC when idle and fans on low?

The lack of airflow might be causing something else to overheat like vrms, or the system might just be unstable and its coincidence like fobose says, i would get hwinfo installed and check all the temps while running some benchmarks and idle.

Are you running the system at stock speeds or overclocked?

This is one of my temps with my fans on silent. https://i.imgur.com/Au9VzcA.png
(Not stress test, but when OS loads up on 100%).

It was a 124 BSOD, usually an OC/Temp issue. PC is set to 4.4ghz @ 1.27v but temps are low and it can run Asus RealBench 5x/Custom x264 overnight/OCCT Linpack or whatever 10hs.

I was thinking something along these lines, that part of the MB is overheating without airflow. Should I run benchmarks with fans on silent, or just benchmarks in 100% mode (what I switch it to when gaming/load).

I enabled my C states after stability testing my OC. Should I disable them and benchmark?

Leave everything in the condition its it when it normally crashes.

What CPU has a Tj Max of 70c?

I don't think this is related to the temp of your CPU. Although you say you don't get crashes when your fans are on... so air flow is helping. Monitor all your temps (you have more than a CPU in your box). Keep an eye on temps of all your components, especially mobo and graphics card.
