Hey, just need alittle help with your wisdom about temps :) ive read a few threads and believe my temps are alittle high and wondered if my pc is stable.

Running Vista 64Bit and believe i have all up to date drivers.
OC Asus Rampage 2 Bundle @ 3.8 GHz ((CPUz and BIOs says its 4009.5GHz) Core voltage: 1.28)
Corsair HX850w
BFG nVidea 285
Antec 1200 Case (when testing all fans on full)
Megahalem with 1 fan directed at rear computer fans

When i built my pc (1week ago) i did everything but the thermal paste and applying the heatsink. since i never did it before my friend did it. he applied 3 lines of paste, west, north, east of the cpu and used cardboard to move it to the center and smooth it all out. i didnt think he used to much but then im rather inexperienced at thermal paste (did it once and it was like inch thick icing on a cake).

Idel temps = 42-46
Prime temps = 79-88(AVG 84-86)
IBT = 77 - 80

Tests Done:
Prime:
Blind test, failed, worker #2 stopped working after failing on rounding. highest temp was 86c on 2 cores.
Large FFTs manually stopped after 8 Hours, passed, temps peaked 88 on 2 cores and 84 on 2 others.
Large FTT Manually stopped after 7 Hours Passed, Temps peaked 89 on 1 core 86 on the rest.
Large FFT BSOD over night, i went to run it for 24 hours, Temps peaked 88 but everytime i checked they were hovering around 84-86.(i know it went passed 11-12hours but i had to do the whole human sleeping thing so dont know when it failed)

IBT:
Stanard and High with 8 threads all passes, temps peaked 80c
Max failed at 8 Threads temp peaked at 80
Max with threads @ Auto passed temps peaked at 80

Using CPUz to get CPU info and Cpre temp 64bit for temps. PC is in my bedroom (student house) and is of nice size, i normally have the window open for testing(however with the 24 hour test i was doing i shut the window and well... slept to wake up in the most comfy quite toasty room ever but with a BSOD :( perhaps the PC just got too hot?)

After the testing and unhappily getting few fails thought id beg for your wisdom :) i normally just lurk and read forums from afar for help but this time if you could answer a few questions would be great.

1) The temps - i know they're high, is it due to the way my friend applied the thermal paste? if so any good way of removing the paste other than using brute force with a credit card?
2)Ill be buying another fan for the CPU (akasa apache) for a push/pull method, how much will this help?
3) looking at BIOS and CPUz info it suggests my CPU is 4GHz, since i only paid for 3.8 and not fussed about the 0.2 GHz would lowing the overclock be a good idea? if so any tips (or is there a OCUK 3.8OC profile i could use?

Any other info would be grand, i havent been able to give my PC my full attention since the build due to uni exams but a month now till 3rd year starts im eager to get this working perfect before then. The PC is used for low detail rendering, Coding, Photoshop, movies and of games :)


p.s. When researchng if it was stable and how to check everyone said prime 95 which i used(and Intel burn test) but no one explicitly said what torture test so i decided Large FTT was the one due to it does Max head and power test thingy. silly question is this the right one?

p.s.s i forgot to ad, after a hard days revision ive been gaming quite abit Trine, Porotype, COD4 single/mult and all on max detail and been running perfect. windows boots in 40-50 seconds(well the windows loading is very fast just a slight hang on the BIOs at start up). Its purely the long term stability issues im wondering about but everything thing seams to be working very well :)

ye the prime temps is very high.

remember when applying thermal paste use one blob paste on the centre of the cpu and smooth it out with a card, i find this better than just sticking the heatsink on straight away.
if you put too much thermal paste on it wont be as effective in heat transfer, make sure its a very thin coating but covers the whole pcu block.

post if you see any changes
 
Hmmm, it sounds like your mate put way to much TIM on your processor.

Here is a link to the Arctic Silver guide on how to apply TIM:

And here is a pic showing how to apply it on an i7 processor.

The test I always use in prime95 is the Blend Test, as it does both Small and Large FFT's, so I find it the best one to use.

Though I prefer to use LinX when testing for stability, as I find it is a lot quicker than Prime, Prime can go for hours before giving errors or crashing, whereas LinX will do it in a lot less time..

I applied TIM to my i7 this morning using the method in the pic above, and my idle temps @ 4GHz with a TRUE are 36c, and full load the hottest core is 80c, and the others are all around 74c..
 
Thanks for the help, much appreciated :) looks like ill re do the TIM once i get round to buying the extra CPU fan :)

If i am unfortunate enough to have a slightly warmer than average i7 would there be a way to get the 3.8 OC settings? another note, how long is the guarantee on the bundles itself?
