I have just built a new PC with the following specs:
Intel 3rd Generation Core i5-3570K CPU (4 x 3.40GHz, Ivy Bridge, Socket 1155, 6Mb L3 Cache, Intel Turbo Boost Technology 2.0)
Gigabyte GA-Z77-D3H Socket 1155 VGA DVI HDMI 8 Channel Audio ATX Motherboard
Arctic Cooling Freezer 7 Pro rev 2
Crucial 128GB M4 SSD - 2.5" SATA-III - Read 500MB/s Write 175MB/s
Corsair Vengeance 16GB (4x4GB) DDR3 1600Mhz CL9 1.5V
BitFenix Survivor, Black, Mid Tower Case with USB 3.0 with Handle w/o PSU
Also re-using my OCZ 600 watt PSU, my 750gb HDD and my GPU (which currently isn't installed).
I had some problems with shorting yesterday, the PC would switch off as soon as it switched on. I had to take everything apart and re-assemble it. Part of this process involved removing the heat sink from the CPU and re-applying the fourth clamp thing as it hadn't been placed in correctly.
After re-assembling the machine I am relieved to see it boots into BIOS.
The CPU temperature seemed high, in the high 40s. I thought this could be normal until it climbed up to 60. I noticed the CPU fan wasn't spinning so I put on the fan warnings in the BIOS. The temperature was reaching up towards 68c at this point. This was over the course of about 10 minutes. I saved the fan settings and rebooted but immediately the computer started making a constant high pitched sound. Is this a fan warning to tell me that the CPU fan isn't working? Obviously I could see that it wasn't but I'm wondering what the sound was.
I immediately switched the computer off.
So where have I gone wrong here? The CPU fan is plugged into the CPU fan slot on the motherboard. Why won't it spin even when the temperature gets so high? The fan is set to auto in the BIOS. The fan spins for about a second when the computer was turned on. I haven't turned it on again since.
How high can a CPU temperature go before it breaks? I reckon I didn't let it get too hot there before switching it off.
