Got home from work last night and thought I'll have a game of battlefield. But before i did that i checked mail, visited some sites etc and i noticed the cpu fan (titan fenrir) seemed to be spinning faster than normal. Thought maybe the wife had been on pc and it was maybe just a tad warm.
Loaded battlefield and i'm about 20 mins when it was very noticeable that the cpu fan was spinning at it's fastest speed possible.
I came out the game and switched on asus pc probe, immediatly the alarm went of against the motherboard which was at 60o, at the same time the cpu was about 64o. After coming out the game and switching of steam etc the temps dropped a bit to M/B 54 and CPU 59 at this point i switched of the pc.

So 10 mins later pc back on the temps are idling at CPU 54o and M/B 50o, now this is clearly not right, as memory serves me my idle cpu was about 38, can't recall the motherboard temp though.

I have a small meter inside my silverstone Ft01 case which says temp in case 31so...nothing scary there.

My system is an Intel i7 920 (not overclocked) an Asus P6T delux V2 M/B, 6GB ram, 750gb Samsung spinpoint and nvidia GTX260Rev 2

So what would cause this sudden increase in temperature? I have done nothing to the pc lately.

P.S. The fans are relatively clean so it's not a dust build up in the case.

Any thoughts please?
 
Sounds like the CPU cooler has moved/not in full contact with the heatsink. During game play CPU loading will rise and hence temps. For a non OC system that temp rise is a little over the odds. Start with a check/reseat of the Titan fenrir and work from that point. Don't forget to re-apply some thermal paste. :) (a stock cooler would be more than capable of keeping this CPU cool if not overclocked, so a Fenrir is a little overkill )

The small meter will only give you ambient air temp, which as it's moving will be a lot lower than some of the highly stressed components... ie CPU, GPU etc... so not a really good guide.

Check out some of the programs in the sticky in the overclocking section for more accurate temp monitoring :)

Afterthought... 60 ish will not harm your system... many of us get up to low 70's with good CPU coolers and heavy OC's

I take your point about 60 not being that high but it is out of the norm for my system.

Another thing i forgot to mention was last night i ran real temp 3 and what was interesting was it only showed 2 cores working. It had the temps for core 1 and 2 and but 3 and 4 were greyed out as if i was usuing a dual core system but as said earlier it's an i7 920 quad???????
 
cpuid HWMonitor is the one I use..not the pro version.

If you change anything in your system.. new drive etc re-install it so the initial installation scan picks up any changes :) i switch it on just after start up and I can get an idea of high/low and current values for the whole session... temps... CPU/GPU/drives etc and voltages etc

Anything out of the norm deserves a second look :)

Ok well i'll remove the fenrir incidentally bought because i was going to overclock just never got round to it, take alook at the connection and take it from there.
Trouble is i don't think i have any Thermal paste left :(

I still don't understand how it could have slightly moved or come away?
 
Just coming slightly loose will cause problems.

If you have the stock cooler?...they sometimes come with thermal paste pre applied. so you could use the stock cooler as a stop gap :)
 
Good point, i may still have it somewhere.

I seem to recall when i set the cpu and fenrir i paid over the odds for best thermal paste i could get but i'm not really sure it actually made much diference
 
Just had a thought, if the heatsink has somehow moved and come away slightly is it possible the cpu would shut down 2 of the cores because of the overheating?

I ask that because when i set up my pc last year i used real temp a lot and it definetly showed 4 cores so the fact it's only showing 2 now is worrying.
 
Sorry for the delay... had to sleep.. night shift :)

The cpu would throttle back when it gets to its max temp, dependent on bios settings not shut down 2 cores only. Probably a software malfunction. Re install and check again. :)

Thermal pastes/compounds do breakdown and become less effective over the passing of time. Therefore need re applying, which may be the case here. As to which type? They all perform within a 5 - 7 degree range of each other, depending on which tech report you read and believe.
 
The Titan Fenrir is a large CPU cooler and heavy weight on the mobo when set in the case. Is the CPU tightly secured to the mobo and not coming away slightly, not too tight or the mobo will snap.
