I have an 'Assassin' build, I built it in Feb 2012 following the guides... ASRock z68 Pro3m, i5, 8GB, 64 SSD + 3TB WD 3TB. No graphics card;
in a Silverstone GD 5 case... 2 extenders (old Linksys DMA 2200). OS is 7.
A few months back the machine started running hotter than normal, as evidenced by the CPU fan becoming audible, (sometimes very). I swapped the molex from 5 to 7 on my case fans. Then, a few weeks after that the Ceton iV crapped out and I sent it back for repair... in the meantime I purchased an HD Prime 3 tuner. I believe this is when the CPU fan really began running fast... I was frequently checking that AS Rock BIOS utility and it showed CPU temps between 115 and 125F, fan was going audibly fast (can't recall the rpm range). This phenomenon would occur even if nothing was running on the machine, TV off, nothing recording... I'd walk by the box and would hear the fans going extremely loudly. Strange.
About a month ago the machine began to crash with an unacceptable frequency, and I started googling around trying to figure out what to do (posted here, I think). Then, one day, it just hung up at the blinking '-' just after the BIOS screen start ('Press F2 to enter set up") and just before the 'Starting Windows.' I reinstalled the OS as I really was at a complete loss (let the machine cool for a few hours etc.) as to what else to do... I could not get the box to boot off the SSD. Probably should have tried to boot off the back up image I made in Feb 2012 - as I said, I followed The Guides.
I think my next move is going to be to remove the HD HR prime tuner and see if that improves it. My other thought was to add a relatively inexpensive graphics card - this is a result of something I read on Tom's hardware concerning Sandy Bridge's relying solely on on board graphics and how problems occur when the cpu is taxed, however, I don't think I'm taxing the CPU (and in general when I pull up it speed because the CPU fan is humming it is frequently running at 1600 or 2300 - meaning it is in power saving mode). I can't find that posting on Tom's hardware right now, but, I remember it coming up on a few different google searches.
I've cleaned the case/fans (several times, air flow is good).
When I check task manager I don't see anything which would indicate that an idle machine's CPU should be heating up to 125F in a case with decent cooling... explorer.exe is the memory hog, CPU usage under 10%.
Can anyone provide any insight or perhaps better next steps to take? Perhaps some diagnostic package to run? The machine is once again beginning to crash, not often, but roughly once every 5 or 6 days (which, it has done since I re-installed the OS).
Again, the two things I'm considering is to remove the HD HR Prime (something I'd rather not do) and/or adding a graphics card (which I believe will trash all my DRM/Copy once recording, so, another thing I'd rather not do). I don't think that 125F or so is too hot but the machine just doesn't seem to be handling it... there is definitely a direct correlation with CPU fan speed/temp and probability of crash.
As usual any of your wisdom is greatly appreciated.
