I7 965 Running hot at idle?!

Hey all,

Been looking all over the place for topics RE: i7 965 but everyone seems to have a 920 out there.
Guess i have too much money haha - jokes, im poor like everyone else. ;) 

But i was wondering WTF is going on with my temps.
i want to over clock this beast but i am worried about my core temps under load and idle.

-Ive got a corsair H70 water cooler for the cpu
-more than the stock fans that come in my case - coolermaster cosmos s
-Ive applied articsilver to the CPU

and my idle temps on a stock 965 are averaging 42C

Also running
-12gb corsair ram
-Nvidia geforce gtx 285

This is my first attempt at getting my hands dirty with OCing hence why im parniod, I cant really afford to go buy this cpu again haha

Ive tried to understand what i hear everyone talking about that my temp sensors could be blocked or something but its in over my head atm as im trying to take all this in.

regardless i would still think on idle i would be getting below 42C, with load i start reaching 75C and all while at stock settings.
I see people out there with OC and getting less than what im getting and not by a little but miles. :( 

Any help, suggestions and comments are more than greatly appreciated.

Cheers

Hello.
You are right these temps are very bad.. definitely something wrong here, with a cooler temps should be real cool.
You cant oc for the time being.
Check that the cooler is well placed. Also, try monitoring your temps with HW monitor. Accurate/reliable.

you have to keep in mind that it is a 45nm i7 these things run HOT! 42c is a little high for idle at stock speeds....I have a TRUE with 2 fans and an OC at 4ghz and i idle at like 36c......I am not sure how well those water coolers really work but i would imagine a little better then that...try resetting the cpu block with some good thermal paste like AS5 also check the voltage on the cpu it should be around 1.2v not really any higher

Yeah, im going to reset the cpu today (again) see what i can come out with.

I previously had the coolermaster V10 but that was just a waste of money and space in my opinion so i opted for the h70 watercooler as im sure its got to be a step up from air cooling.

ive used AS5 and using it atm but how do you know when you have applied to little or too much ?

the voltage on the cpu is lower than 1.2v, ive set the optimal default settings in the bios to make sure everything is a stock as possible except ive turned off turbo boost.

couple other question/food for thoughts.
Why/is it normal when booting up and jumping into the bios and looking under pc health status that the cpu temp is around 32C-35C but then by the time windows has loaded that my temps are 42C? i dont have much if anything running in the background.

Also my cpu fan ive set to run at full RPM as well the pump is showing that its running at full RPM when i have it plugged into a second fan header.

Also with the h70 it has a push - pull air flow system.
ive heard of ppl mounting it so that i pull cool air from out side the case pushing it through the rad and into the case and also the complete opposite of pulling the air from within the case out through the rad and the back of the pc.
anyone found some conclusive results suggesting which is best?

Also any thoughts on air flow for the case? is it best to have all the air go in and out one way or have air coming in from the back, front, side and all exiting the top obviously cause hot air rises. Thats how the case is atm

Thought id attach some pics just for fun :) 
(the white arrows are where fans are and their directions)

1). Applying thermal paste is almost like an art its not easy to do right....I would stick to either the method of spreading it with a plastic bag all over the heatspreader or jus make a decent sized line across the cores.....you cant really have TOO much thermal paste because the excess will be squeezed out the sides of the heatspreader when you put the cooler on

2). The reason for the temp difference is that the bios uses a temp probe that is on the motherboard not the cpu itself so it is giving you a less accurate reading...programs in windows uses the temp sensor on the cpu die and calculates the actual temp when given the distance to TJMax

3). I would suggest having the fan push and pull outside the case so have the air blowing outside the case....if you do it the other way around it is bringing in "cooler" air from the outside but it is also disrupting natural flow of air thru the case and it really isnt going to be a noticable difference.

4). Your airflow pictures look good you always want to go with natural flow of hot air....one thing to think about is that if you have more intake fans then exhaust you will have positive air pressure in the case which will force dust out so you will have less dust and crap building up in your system

5). Good luck with the temps let me know what happens it could also be you just have a hot chip which would suck but it seems like your doing things right.....one last thing make sure the hoses to the watercooling are not too cramp you dont want to accidentaly crimp anything that would cause a big temp increase

So ive taken the out the cooler

-re-applied AS5 and just wiggled the cooler around until it covered the cpu.
-swapped the direction of the cooler fans on the radiator to push and pull air from within the case to out side of the case.
-also swapped the side fan and bottom case fan to pull air out of the case. reason for this was the power supply is on the bottom pushing its air out under the case. and the basically the bottom case fan which is next to the power supply was just sucking it back into the case.

and its dropped the temp by about 2-4 degrees maximum, not a super result after going through all that effort.

Does AS5 have like a break in period?
where by you have to run the comp for a little while till it really takes effect?

sorry it took so long to respond i have been busy....yes AS5 drops like 2-5c after 100 hours or so of heat cycle.....it could just be that you have a hot i7 on your hands...its unfortunate but it happens.....as long as your vcore is where you say it is there isnt really much more you can do
