Are these temps good for my Core i5 2300 ?
May 14th, 2014
=Mobo: Biostar TP67B+
=CPU: Intel Core i5 2300 2.8Ghz OC’d @ 3.4Ghz
=Cooler: Stock intel cooler
This is the first time i’ve tried overclocking, so I’m a bit of a noob at this…
I used the O.N.E bios overclocking utility for biostar mobos.
Multiplier: From 28x to 32x
Base clock: 100mhz to 105mhz
Clock speed after changes: 3480mhz (avg)
And normal usage temps are:
Avg: 39’C
Max: 45’C
Full load torture test using Prime95 (In-place large FFT’S) Temps:
Min: 59’C
Avg: 65’C
Max: 74’C
I’m not sure about these temps, they seem a bit high… Any suggestions?
Thanks in advance
No, the temps seem high. Even the idle temps are comparatively hot enough.
Check if the heat sink is properly seated.
Use a good TIM
Have a fan of two in the rear pushing air outside the case
Cable management to insure good airflow in the case
How did you overclock that anyway? Via the bclk?
Sorry lol, got the normal use temps wrong.. here are actual temps:
And normal usage temps are:
Avg: 39'C
Max: 45'C
The heatsink/fan cooler is seated properly, and i have this cooling it:
1x intake fan 120mm (front of case)
1x intake fan 120mm (side window of case)
1x extractor fan 120mm (top of case)
1x extractor fan 90mm High RPM (side of case)
What do you think about the full load temps, are they too high? What would you say I should try and get it down to?

I think there is a positive air pressure in the case. To keep a case cool there should be a negative air pressure inside. Change the direction of one of the intake fan to make it exhaust. I would recommend 2×120 as exhaust and 120+90 as intake. You can read about it here:

Also make sure that your CPU fan is running at 100% on load. Sometimes a BIOS or a software throttles it to keep it quieter. Also, clean the fans and the heat-sink as that might be slowing it down.
And what voltage are you feeding your chip? Lower the voltage and run a stress test. Continue lowering until your system get unstable. Then use the lowest stable voltage.

Negative air pressure doesn’t keep it any cooler and the only thing it will bring forth is more dust. Positive air pressure is the de facto standard for all applications now.

I’m still quoting the relevant part for you,

6. Positive and Negative Pressure
Positive
If you have more CFM coming IN, then OUT, you will have hot air cycling in your case waiting to go out, called positive air flow. However, most hot air will be pushed out through your available exhaust fans.
The benefit of having a positive pressure case is that all of your intake air is being cycled in strictly from your intake fans which should have dust filters installed. Therefore, a positive pressure case tends to have much less dust then a Negative pressure case.
Negative
If you have more CFM pushing air OUT than IN. This makes a negative airflow.
Basically you need more air OUT, then goes IN using the fans. The additional air needed will be sucked through the mesh and other holes in your case. The benefit, in theory, is that more cold air is being pulled in through the extra gaps and therefore keeping things cooler than a Positive pressure case.
Don't Go Overboard
Too much of one pressure can be a bad thing. Too much positive pressure can cause turbulent air inside your case and create pockets of hot air that can't escape in parts of your case. Too much negative pressure can prevent some components from getting any air flow at all. Try to attain a mostly neutral air pressure with a slight pressure change towards the pressure type you want to gain the advantages of that type.

In reality it just brings in more dust with relatively no impact to the temps. I’m not new to OCN I have half the number posts I have over here there.
