New to Over clocking and Prime 95

[Peppered]

Have a I7 920 oc to 4084 Mhz right now and running prime 95 using the first option test in the torture test.
On speed fan I show core temps to be between 56 and 62 deg.
On Core temp I am showing 71 to 77 deg .

I am testing to see were I can be stabel at before I get my new case and drives in the case showld help with my temps. The new corsair 800 case. I also wanted to try out there Water cooler for the cpu to see if dose better that the fan and heat sink I am using now.

The temps core temp show kinda scare me but that may be ok for a stress test. that is were i am not sure. If the temps are to high during prime 95 test let me no so i can back down the speed to 3.8 before I fry somthing lol.

See the problem with temperature measurements on a processor is that the temp probes do not actually report the temperature in *C or *F. Instead they report to software the distance to Tjuction Max. Basically Tjmax is the temp at which the processor starts throttling itself. So temp software like core temp and speed fan convert the distance to Tjmax to *C all good right? Well unfortunately Intel does not publish what the Tjmax is, and ive heard that it can vary core to core anyways. Some people have gone out of their way to use laser temp probes to try to measure the core temp and correlate that to Tjunction, and most people believe that the distance to Tjmax is around 100*C on i7s

I know for a fact that HWmonitor is wrong (its temps report about 10*c too hot); speedfan also sounds like its off (looks way too cold)
Core temp looks pretty good, but what you need is something that reports temps in Distance to Tjmax like Real Temp

It kinda blows because Intel publishes what the safe operating temps are for Tcase (measured like 380 microns into the integrated heatspreader)... well guess what, there is no temp probe there... so basically all we can do is guess

Over on extreme systems some people say 30+ Distance to Tjmax is fine for 24/7 use; while ive heard others say that you cant kill a processor based only on temp if the processor can throttle itself (only from voltage and electromigration)


This is pretty interesting:

Basically they take the heatsink of a p4 while playing a game and it still runs, the p4 was the first processor from intel that thermal throttled, but as u can see it still survives with no heatsink (prolly not safe for 24/7 use)
lol at the amd going up to 370*C, thats awesome

Thamk you for the very detailed info.
I went ahead and ran Prime 95 for 12 plus hrs and it came up with no errors.
So I guess I will be safe.

I dont have the best cooling just 1 120 mm intake and 1 120 mm discharge. The side fan on the case made to much noise for me use.

I Have a Corsair 800 D case on the way alomg with some new hard drives.
I also oreder the Corsair water cooler to see if that helps with the Cpu temps I have seen bout good and bad reviews on it. I belive as long as I hook it up to wear the rear discharge fan is on the case and then reverse the flow of the fan it should get cool freash air and should work good. I will also wount three disgarge fan on the top of the case this will make up for the one I swaped the air flow on.

Realy looking forward to the new case along with a 60 gig SSD boot drive 300 gig raptor for the app drive and 1.5 terabit drive for saving vids, pictures and doucment too. I should see and big improvment in the way my PC responds.

Next big step will be full blown water cooling but dont have the cash left to do that yet.
