I've built a new system but it keeps overheating. It will run fine in the BIOS but as soon as I start something more intensive (like attempting to install the OS or using a live edition) the HSF's RPM will increase drastically accompanied by a lot of noise after a couple of seconds which, as far as I know, indicates that the CPU's getting hot. After another couple of seconds the blue overheating LED on the front will light up and the BIOS overheating error beep will annoy my ears.
After searching the internet I found three possible causes.
- bad airflow due to blockage by wires or failing fan(s);
- dust buildup;
- incorrect mounting of or damage to the heat sink.
I've included a picture of the system so you can see the airflow for yourselves. I think it's perfectly fine and all (four) fans are running. Of course, seeing as it's a new system, dust build-up shouldn't be any problem.
So I thought the heat sink is the problem and removed it, inspected both the heat sink and the TIM for any damage but could not find any. I remounted it and made sure it was on firmly but not too firm. Yet the same problem occurs.
In the hope that it would work I even opened up my case and let it run with a desk fan pointed at it, yet it still overheated.
List of components:
- Supermicro Case MT 500W CSE-732I-500B Black
- Supermicro MBD-X9DRL-3F-O Dual LGA2011 motherboard
- Supermicro FAN-0124L4 12 CM 1850 RPM additional front intake fan
- (1×) Intel Xeon E5-2620 2.0 GHz hexa-core processor
- Supermicro SNK-P0050AP4 3800 RPM active heat sink
- Western Digital WD7500AZEX 750 GB 7200 RPM hard disk drive
- (4×) Corsair 8GB DDR3 1333 MHz RAM card.
I tried to figure out the cause and made a few attempts at fixing it, but I have simply run out of ideas. Please tell me what you think might be/is causing the issue.
I've uploaded a picture of the system so you can see it and maybe judge the airflow:
I've found a somewhat new problem. Now it also turns off in the BIOS but there's not overheat LED nor error beep! Do you know what's going on?
