Why?

I just overclocked my E6400 to 2.8GHz. I did this by setting the FSB to 350. I have a question:

1. When windows starts the CPU Temp is around 70C and then goes down to around 67. When I ran prime95 temps went up to around 78C. I ran it for an hour and got no problems. That ok?

Are you still at stock voltage? There's a lot more involved in overclocking than just changing the FSB
 
I would not like my processor to run at 78c...that is really warm actually. What CPU cooler are you using? Is it the stock Intel one?


I would consider opening up the airflow in the case and replacing the stock TIM with some OCZ Freeze or Arctic Silver 5. A new application of one of these can drop temps by as much as 10c.


What case do you have? A few extra fans would also help a ton if the air is not moving in your current setup.

Yes I have a stock intel cooler, it has like a pipe directly on it leading to an opening in the case. The case is an akasa basic one. Do you think it's better if I remove this pipe???? In the case there are 2 big fans one at the front and one at the back.

What? Got a pic of the cooler?

Are the fans working?

Yes fans are working fine. The cooler is a normal fan/heatsink one however attached to the side of the case there is like a 'chimney' that goes from the top of the cooler to a window in the case. I don't know if that came with the cooler or the case because I boght my computer ready built.
 
It could be that one of the Intel "push pins" has popped out. It happened to me a couple times. It will shoot temps way up. Make sure the cooler is evenly seated and tight.

I would also replace the thermal interface material if I were you. That's not much of an overclock to cause temps like that. I would bet a little AS5 and temps will be much better.

But temps shot up only when I ran prime95 and I know that treats the CPU quite badly. With normal windows running temps are only around 66-68C. Anyway I will open comp and check.
 
I am calling an improperly mounted HSF or that it's overloaded with thermal paste... or just bad quality paste.
 
agree with comment noted, check hsf, replace thermal paste and re-seat hsf. Ditch that stupid chimney i never liked them.
Did you up the voltage? if its still stock voltage then the temps look too high
 
I did not change the stock voltage. What will I look for in the BIOS and by how much will I change it? And how much paste is enough?

Today my computer has been on since morning (so almost 12 hours, running windows application and online radio stuff) and the temp is 64-65 C. Tomorrow I will open up computer, check the cooler and remove the chimney and see the difference. Also the BIOS had an automatic overclocking function of 10-30% and maybe I will try to overclock that way and see performance and temps.

Thanks

if your rig is running fine at that oc then there is no need to up the voltage.
Can i ask a silly question....but why are you oc'ing?

also if you push you fsb back to default what are your temps like?

I will try to put the fsb to default and check the temps.

I am oc'ing because in some games like NFS Shift the performance is not that good. When I did the 3dmark test the CPU was the weekest part and the score was low. With the CPU OC the total result went up by 16%. I OC-ed the video card too and the total mark went up by 22% (from the original default settings). Not bad I think.

that is a decent improvement. Just checking you actually had a reason :)
check those temps, but in your mind id be thinking of upgradeing from stock cooling or at least changing the paste. There a chance the hsf its sitting right, but its not that common an issue

I will check tomorrow and maybe order some good paste from ebay and replace the one that I have (somebody told some arctic 5 is good). I cleaned my computer around two weeks ago, bought paste and put the whole damn thing, well it was not that big (like a syringe) but maybe I put too much.

Well maybe I created a reason to OC. I love computers and I am not an expert however I like to learn and experiment. Anyway the CPU is 3 years old so if it fries it's not big deal.

Once I fried a mobo and I think I did it by spraying the air cleaner wrongly (not keeping the can straight). Luckily it was still under guarantee :-) But I guess we learn from our mistakes.
 
You really need only a small amount...maybe the size of a grain of rice.

You said you had some and used the whole syringe? The idea is to create a very thin layer that helps transfer heat from the CPU to the cooler. The thinner the better:D

Make sure you clean the surface on the processor and heatsink very good before applying new TIM. Rubbing alcohol will work...they have specific special cleaning solutions for it actually...but you'd have to order those.

Remember...very thin layer. Here is a picture of a graphics card I did. Imagine all of the chip and the green part in the picture is the top of your processor. Just a small little amount in the middle is all you need.
