I have bought the mugen 2 rev b a few weeks ago, replacing it with a Arctic cooling 7 rev b that didnt cool it enough. and I also bought a new case named CoolerMaster 690 II Plus.
My Core temperatures are even.
Max Load: 58
Now I wonder, if I bought a big and with vgood airflow case, and a big CPU cooler and installed it with MX4 correctly, how is that my cpu is quite hot... I mean I should be able to OC with this rig right?
I'm in this for a while and I've tried adding the paste this way, and that way, checked a lot of tutorials that didnt make a difference.
My Volts are stock: 1.34V
I also have a 460GTX which runs on the same temps:
While testing CPU:50+-
In my case if you saw it before, has 3 fans, one on the front, back and top.
I can say that the mugen is well airflowed since the top and the back are pulling out the air while the mugen's fan pulls in. its like adding 2 fans because they are really close to it.
I have cable managed the case pretty good so it isnt a airflow problem.
and my room temp can be 25'C or less.
And the most important question:
If I want to OC, lets say I get 3.8... will the temperatures raise like in 5 degrees? or as long as I dont touch the voltage it wont be much of a difference?
Its very important to me if you read it all so you know all the details.
Any suggetions are very welcomed and I will apreciate any help you guys can give.
I would expect your CPU to be running a few degrees cooler if you have proper airflow thru the case and the room ambient temp is reasonable at 25C. Have you checked the fan speeds to be sure they are running at full speed under load?
If you increase the CPU frequency without changing voltage the heat generated will increase and the CPU temp will increase some. With a voltage and frequency increase expect the CPU temp to increase significantly under full load as the HSF doesn't seem to be doing a great job if your temps are correct. Are you using Core Temp ?
As far as TIM is concerned, you want the absolute thinnest possible layer as TIM is actually a thermal insulator compared to metal-to-metal contact. Most people use WAY too much TIM. It should be almost translucent as it's only intended to fill the minute imperfections in the HSF base and CPU heat spreader.
actually nothing happened, I had the stock cooler before (very noisy btw) and I played for a few hours without problems and the CPU got to 70'C usually... but in the AMD site it says max safe 62 so I didnt want to get there...
There is something wrong somewhere as your temps should be alot lower with that cooler. I suggest try reinstalling the cooler as you most likely have to much or to little thermal paste or just bad installation.
The 945 comes in 95W & 125W TPD while the 955 is 125W. There would definately by some temperature difference but I don't think it would be more than 10C my best guess it would be 3-6C ish, but it would even vary slightly just comparing 2 955s.
I ask because my brother has the 945 with AC FREEZER 7 and I got 955 with MUGEN 2, my CASE has more airflow and I got more fans in the case. and still my brother's CPU gets on max load to 47-50 not more while my gets around 57-60
Well, with stock I had 70, with AC7 I had 67, and with this one I have 56.
so I think its a pretty good upgrade.
Though I think you are right, it should be even cooler... I dont know what it could be. maybe its a bit more then 25'C I just guessed from what I feel.
sometimes it gets hotter but at night, or day its the same CPU temperature.
k this is what happened this few days.
After I OC'ed to 3.6GHZ I tried to get to 3.8GHZ...
I tried with stock voltage but it crashed my pc when I ran stress test...
and so on until I got 1.45V, the problem is that when I Stress test the CPU gets to 65'C!
So, I've cleaned the Thermal Paste (MX4) and put some new paste that I had left, temp difference is 1'C more or less difference for now.
The method I used was to clean the cpu and cooler with alcohol until its clean, then I added on a few spots on the cpu a little paste and spreaded it with a credit card, I didnt used to much, just a thin coverage.
What do you think? The Temperature will change after the paste cures or something? or this is the situation im stuck with?
I also though about a few different posible reasons\fixes.
1. Could it be the Mo'bo's sensor that aint showing the correct temperature?
2. I am planning on adding a Scythe GT 3000RPM (dont mind the noise much) instead of the 1450RPM stock cooler...
3. Could it be the cooler who is bad created from the factory?
4. Is my mo'bo good enough to OC above 3.8GHZ? and can a better Mo'bo let me OC to 3.8 with stock voltage?
and last question: What is CPU NB? and can I OC it too? and if so, how does that help me and my CPU?
I hope you got patient for me, and dont mind my english I know I dont speak\spell very good but I do what I can XD
Thank you very much for the help, hope I can get some answer from experienced people here XD
