Does 54C sound decent at full load running OCCT? I have an older Lian-Li that doesn't have a top fan or side air intake so with the door on I get higher temps. If I take the side panel off it drops to 48C at full load via CoreTemp. I want to leave the side panel on and I doubt I'll be running at full load very often.
 
Stock cooler? Fancy air cooling? Water in the system?

Either way the CPU throttles at 85 Celcius, if you are loading under 65, and you are apparently, then you're safe. Personally I load at 62 Celcius with a modest OC.
 
Zalman 9700. Like I said, with the side panel off I stabilize at 47/48C after running OCCT for a while.
 
same cooler here with 6600 on 680i and occt/ortho around 52-53. So I'd say thats about right. This is with an overclock to 3.2 @ 1.35v

The C2D is a tough little chip and can continue running at over 80C as long as the MHz and volts aren't too high. Mid 50C is easy street for the C2D.

unclewebb, TAT reports MUCH higher temps on my DS3 than either core temp or speedfan. 10 to 11 degrees higher! Screen cap coming as soon as the temps max out...gimme a min...

ALSO, if I use the built in TAT work load simulator....temps go up even MORE...I am showing 82c right now???? ORTHOS running only gives me ~72c ....????? Which one is right.....

OK, I found the issue, no wonder I was unstable at 3.2ghz the damn thing was overheating a bit, I re-applied AS5, and found the heatsink was attached too loose!!! I tightened my Big Typhoon down quite a bit, it is actually warping the mobo a bit, same as does the stock cooler....no worries there, I have seen some stock solutions bend the shit out of the mobo. I am running the exact same speeds and voltages as the previous pic, but I am seeing 10c to 12c temp drops!!! HUGE difference in temps.....but still, TAT and the other two programs report a large variance in temps! Wonder why that is.....fixing to test again at 3200mhz....

The cpu just shuts down as I found out last week playing at my buddies house.... I was probably 15-20mins in the game when it happened and was like WTF, then I saw my cpu fan got unplug somehow..... The ultra 120 got so hot you can prolly cook an egg on it lol..... Cranked the fan and let it cool down abit and she was good to go .....
 
OK, I am going to run orthos overnight, here is a pic of the cpu back at 3200 and running nicely....temps are rock solid steady and well within limits.....vcore is ~1.36v idle and 1.35v under load....

TAT3.jpg
 
67 is still a bit high for 1.35vcore....

You are not the only one to have these problems. My friend's lapped e6400 idles in the low 50's yet loads in the high 50's. (hes got a Zalman9500) It boggled the hell out me.
 
The beauty of not using a case:D ..... vcore set at 1.6v but it should be in the 1.52-1.54v range after the droop.....

Cool, I did not know that you can already get LN2 setups retail.

:D - one sweet OC you got there - what cooling?

That's right... Mine is running at around 65C during Orthos but this is at 3380 MHz and 1.475v. Yours is too high so recheck the thermal compount, mounting and such.

I already did that and dropped 10-12 degrees, that is the result I have now. You don't understand, using ORTHOS, I only get 65c-67c, if I use the TAT cpu loading, it gets ~6c-8c HIGHER, seemingly loading the cpu even more....and I have a thermaltake tsunami case, very quiet, I get 3c-4c lower temps with the case cover off, but I don't run like that. I hate loud cases!


You have to use TAT to load the cpu, see if you get any higher readings than with ORTHOS....at this point I do not know which one is correct...

Sorry, I misread it a bit and TAT is indeed pushing more. I was able to reboot my computer at will just by running TAT and pusing the temps close ton Tjunction. However, it's pointless since nothing will ever come close to pushing that much as TAT. OCCT and Orthos is a more realistic stress test because when I'm folding, i'm generating 5-8C less than Orthos the majority of the time.

Yeah I can run stable at 3.2 with ORTHOS, but TAT will crash my rig after about 5 minutes, Folding also is 100% stable at 3.2....here's a good one....why does my coretemp and TAT show different temps? For the record, Speedfan 4.32 also shows the same temp as coretemp...this screenie is loading the rig using ORTHOS only....

EDIT: I am back at 3100, testing slowly upwards to find my best speed at lowest voltage....if it passes everything at this, I am going to bump her up another 20mhz and test some more until I hit a stable 3.2 or it fails....

I dont think TAT is putting a load on your computer, its just reading the temp in a different place than coretemp and speedfan.... I think of Coretemp and Speedfan are the most accurate, but from what Ive seen with mine TAT under load was only 2-3c higher....

TAT will load the cpu even more than ORTHOS will.....guaranteed, and that pic is JUST ORTHOS running, TAT is not applying a load....what I am getting at, is why do I have such a large discrepancy between core temp (regarded as the most accurate) and TAT (also regarded highly).
 
On some boards TAT is about 2C different than CoreTemp which is why TAT has this undeserved reputation as being so accurate.

The problem is that on other boards it is generally about 12C higher than CoreTemp. In this case TAT is WRONG.

SpeedFan v.4.32 that displays core temperatures and CoreTemp are in complete agreement on all boards that have been tested so far so don't put too much faith in TAT just because it has the nice Intel logo on it.

TAT was designed for laptop testing. It has not been updated for the C2D processors or for all of the motherboards now available for the C2D.
 
I don't even look at TAT. SpeedFan, CoreTemp, and Gigabyte EasyTune are all in agreement, so that is good enough for me. TAT is that 1 out of 4 dentist that doesn't recommend Dentyne I believe. :p

That is good news, and glad to hear you respond, you seem well educated on the matter and provide great backup. So I can safely assume my cpu is not running 70+ celcius at only 1.36v and 3200mhz?

I will go with what coretemp and/or speedfan provide, they are within 1c of each other typically....
 
I try not to jump to conclusions without doing some thorough testing and from what I've seen, CoreTemp and SpeedFan v.4.32 are showing us the numbers that we need to believe.

The Core2Duo has a built in thermal throttle that kicks in to keep its core temperature at a maximum of 85C. When the cpu hits this temperature it slows down as much as it has to so that the core temperature doesn't go beyond this level. If the temperature is spiking up in a big hurry then it will simply shut down before it even reaches 85C.

Anyone can test out the throttle on their cpu and motherboard like I did but if you think taking your new chip up to 85C is nuts then I guess you'll have to take my word for it!

Intel would not rate their processors to be able to handle a core temperature of 85C if they couldn't. Big companies really don't like getting their asses sued for false product claims.

85C is a big number but Intel's laptop CPUs can run even hotter. Some of them are rated to run reliably up to 100C. Now that's hot, especially when it's on your lap! :eek:
