47 on the MB is too high I think, try better case fans? Not sure if WJA has the side off his case maybe. 63 on coretemp is fine imo, I run upto 70 with no problem

I hava an akasa mirage with scythe 1200rpm fans at the front and back so I would have thought the case cooling was adequate. I have a 40mm fan which I am going to attach to the h/s on the s/b and see if that makes any difference.
 
Your at a similar speed to me so I dont know why it would be running hot for you.
But if its stable at 47 then good. I have orthos on and its reached 39/40c in the last 20 minutes, not that different to idle since the fan speeds are fixed pretty much.
I have 2 120mm intakes and 1 for exhaust along with 2x 80mm. They are all running low speed, 5v or so

Previously I had the SB reaching 43c and appearing to be unstable because of it. Ive got some metal on top of it as a crude heatsink, I dont think its stressed under load particularly so Im not clear what part it plays exactly.

Probably the NB temp is much more important but theres no sensor near that so it gets ignored more then it should. Mine is painfull to touch but not quite burning my skin yet :o
My mum has 3 cooking turkey type thermometers so I have liberated one and I shall tape it to the NB in a minute after I switch off the machine otherwise I'll no doubt shortcircuit something. It measures 50-200c

Taking the side off the case lowers MB to 37c and this temp is confirmed correct with another flat plastic therometer I nicked from the medicine cabinet lol :o

No, the case side is on, but it is a V-series Lian Li so it has very good passive cooling with all those holes drilled in it. All the big heat sources in my case are water cooled, so there is really nothing to bring up the internal air temperature and the power supply is directly vented to the outside.

If taking the side off your case drops the component temperature by that much then should you be looking at your airflow? It's almost like you have dead air in the case that isn't allowing the passive components to cool adequately.

I have seen 'overheating' systems where the (large number of) fans are just pushing the hot air round and round the inside of the system.
 
I could improve things greatly by buying another case but its not in budget at present unfortunately.
Maybe I'll pick up an old monster tower at some point. Basically everything is too cramped at the moment.

On the good side, I shoved the cooking temp thing into the NB and it looks well ghetto. Its not even showing 50c yet at idle, accurate ? not sure
The flat medcine therometer shows 40c

Also I ramped the QDR all the way from 1377 upto 1707 and it worked fine first time. Blue screen on the way into windows so I tried again with higher NB volts, its now at 1.7v
Stable in windows and I havent tried orthos, etc yet
 
I'd agree with that, under superpi NB is showing 100F or 40 something celcius.

Its not that impressive a time because this is a budget machine with £50 of ram that barely clocks but I got a new best superpi so for reference heres the screenshot

Its definately a case airflow issue, I just have stuck a 80mm fan into the case pointing at the s/b and temps have dropped by 15 degrees. I also removed the heatsink as it seemed to be more of a hinderance than a help.
 
How come your super pi time is 18.8s on a 3.5ghz core 2 whereas mine is 16.7s on a 3.05ghz core 2? Does the extra cache of the e6600 make that much difference?

Seems very strange!
 
No this board is async and my main memory is very slow, almost stock. Thats the main difference. I might upgrade later but this is what Im using for the moment and Im seing what the cpu overclocks to, regardless :)

I did 32m in superpi on the above setup but it would not stablise in orthos even with 1.5v in the bios and +100mv. So Im back down to 1707 QDR for the moment, orthos stable.
I'll put the side back on, leave orthos for a while and see just how appropriate that oven thermometer is :eek: :D

edit:
40 mins on orthos with the side on gave
115F on NB
42c on the SB
73c on coretemp!
and the stupid AC 7 fan is still not at full speed..

Its not adjustable so I turned it off and it runs full speed all the time now, 2636 rpm. I'll do that in future for orthos testing. Qfan doesnt run it at full speed ever because the sensors are underestimating too much I guess.
Its dropped coretemp by 10 degrees :)
 
Haven't did a system change in a while.

So it's:

nVidia 650i platform drivers
graphics card drivers
everything else

As i'm moving to dual core from a 3700+ single core, what programs will be essential? I've alreay d'led Orthos SP2004 beta (latest version?) and Coretemp, but is there Intel drivers I may need?

TAT obviously doesn't work with nVidia boards. :(

Ive just made that move :D
Orthos and Coretemp are the only ones ive used.
i also gooled for intel dual core optimisation (or whatever its called ) and run that. Didnt know if i needed to.
