*sigh*

I got a E8500 for my PC last week (E0 stepping), and It ran kinda hot so I decided to ditch my Big typhoon, and rather get a Thermalright TRUE, coz i really want to start overclocking it!

So I did the install today after lapping the base of the HF to a perfect flat finnish, and mounting the Cooler by tightening all the screws to the max. (its got really good contact)
I used OCZ freeze for thermal compound. And I also attached 2x120mm fans in push-pull configuiration.

Lets turn the pc on....
I was absolutely crushed to see that the TRUE made absolutely NO difference in temps, and its still high as before....:(
So now my temps are EXACLY the same as before, 46 Idle, and 56 load.
When I run prime95 for a while the temps max out at 61 degrees:eek:
Next, I tried to do a Small OC, from 3.16 to 3.2, just to see the idle temp rise to 50. Something is seriously wrong.

The only thing I can think is that I applied the thermal compound wrong, but Im 99.9% sure I did it right.
Can you guys PLEASE suggest something I can do to fix the problem, Otherwise my E8500 will never see a Overclock.
 
What are you using to measure the temps and how much compound did you put on the cpu ?

Also possible that the TRUE was fine ie concave/convex enough and you have now messed that up (possibly lap cpu as well to make sure this is not an issue)
 
What kind of cooling do you have in your box?

2 120mm fans in this heat won't do shyte for your temps. Maybe get a decent box with decent cooling options. no point your cpu cooler sucking in hot air from your vga card and north bridge, you need something moving that air around.

As QX says what are you using to measure the temps?

The CPU's surface is amazingly flat. I was amazed to see how good the contact was between the 2 when I checked before I installed anything. Im pretty sure there is Excelent contact between the 2.
I used only one small line thermal compound in the centre of the CPU, following this guide: http://www.arcticsilver.com/pdf/appinstruct/as5/ins_as5_intel_dual_wcap.pdf

Ive tried using coretemp, realtemp, everest, HWmonitor, all says the same:confused:
 
Was your E8500 lapped as well...? Im asking because I have a Q6600 and I remember that the Thermalright I have (ultima90) has a natural curvature that fits the CPU(which apparently also has some curvature). It may thus be possible that despite what you think there isn't 100% contact..? Also found that when i installed mine I had to insert cardboard washers underneath the cooler because even when I tightened it completely it was still loose-ish. Which then called for yet another remount.

Ive got a Coolermaster 690 chassis with 5x120mm fans throughout the box, excluding the 2 im using for my cpu cooler.
MyGFX card also has aftermarket cooling, idle is 38degrees.

Sounds strange, i usually use the half grain of rice method in the center of the heat spreader and i let the cooler spread it for me.

If you remove the cooler is the compound spread out equally ?

Im familliar with the "washer mod", will try that tom, My cooler is really tight though, i cant move it at all
 
Or maybe u just having a bad week like me where my temps just shot up 8 degrees for no apparent reason due to the damn heat wave.

Get an air con or air cooler for the room ,trust me it helps :D

Same here.My GFX card went from 49 Idle to 58C. It has not been fun:eek:

I reseated the heatsink earlier, and when I removed it the TIM was spead out textbook style on the CPU.

Im beggining to think:
1. dud CPU
2. Temp diode thingy is incorrect.

FFS, its 11.30p.m and my CPU is at 45degrees, From what I read i should be getting high 20's, low 30's at least. Im soooo Furstrated arrrrg!!!!

I know my ex E8400 always showed temps in the low 30's at idle and only changed when i started putting load on it and with my TRUE they woudl generally peak at around the 40's under load. So could be a faulty sensor but then your load temps seem way off for a non oced machine.

Have you updated your board to the latest bios and if so reset your bios to original settings and see if anything changes (shooting in the dark here)
 
Im getting 60degrees load temp, with an good/great CPU cooler, in a box with good ventilation, with pro Thermal compound in the middle of the night.

Imagine i use the stock intel heatsink, in the middle of the day @ 100% load.....KABOOM!

Does anyone know what Intel's policy is regarding CPU's like mine, unstable hot temps?
Will they do a swop out or something???

Just did that, I thought that my Vcore might have been set to something insane from my previous Q6600 OC, so I double checked that everything is set to 'auto', even loaded the default settings to be sure.... no change...

All they will say is that it is running within the thermal specs for the chip so just carry on (they do not care for ocing so no point mentioning it to them)
 
Dude do you have a normal 3 speed fan, put that in your box and see if there is a difference, its all good and well having 5 fans in your box but if your airflow is not right those 5 fans can actually make your box hotter.

What do you think my temps would be with stock intel heatsink @ 100% load. I swear my pc will just blow up. That cant be "within the thermal specs"
