Hi,
I just built a new HTPC system and I'm currently experiencing extremely high CPU temps under load. Here is my system:
Silverstone Grandia Series GD05B micro-ATX case (3 Case Fans)
Intel Core i5 2500K Quad w/ stock CPU cooler
Gigabyte Z68MA-D2H-B3 motherboard
8 GB G.Skill Sniper DDR3 RAM
Using Artic Silver.
I currently have the BIOS set to load optimized defaults.
At idle BIOS reports the following:
CPU Fan - ~1935 RPMs
Sys Fan - ~640 RPMs
CPU Temp - 63 degrees C
Sys Temp - 36 degrees C
Smart Fan is disabled in BIOS for maximum RPMs at all times. I had this BIOS option enabled and it never increased past~1700 RPMs (idle or under load)
When I run any applications that put this system under load (ie. Freemake Video Converter) all 4 core temps shoot right to ~90 degrees C at which time I have to quit the application. I've been monitoring the temps with Core Temp.
Should I suspect the motherboard is not putting out enough voltage to drive the CPU fan or maybe the stock fan is broken? It seems to me the RPMs are rather low at idle (1935 RPMs). After googling it seems I should be seeing between 2500 - 3000 RPMs at max for the CPU fan. I found this post earlier and it sounds like this person is having the same problem as I am. Same motherboard and CPU.
