Results of overclocking - too hot?

post #1 of 62
Thread Starter 
Hello...this is my 1st question post, so apologies if i do/say anything wrong.

I've recently started o/cing with the help of other forums. But there seems to be arguments as to what temp limit is safe, before you should stop o/c. Some say 60C is max, some say 65C, some say 70C and some say even 80C is not a problem because if the CPU became to hot, it will start throttling. What do you experts say about this? What is the limit?

Below are the results of me o/cing and the temps are different for both programs - Intel TAT and Core Temp..I would be most grateful for peeps advice as to which one program should I follow and are my temps too high?

stock speeds and temps ranged between 51C to 55C MAX!!

Here are the results of the quick orthos tests (upto test 6) i did just to see what max temp the CPU would reach:-

@ 2100Mhz, I got 57C Max!!!:



@ 2240Mhz, I got 60C Max!!!:



@ 2378Mhz, I got 62C Max!!!:



@ 2520Mhz, I got 63C Max!!!:



@ 2588Mhz, I got 66C Max!!!:

I'd deffinatly stay below 65°C Personaly I stay below 55°C for a good life span for my parts. =3

60-odd is too high imo, low 50's is ok... but i'd prefer to keep it below the 50 mark. I'd say going above 55 starts to become dangerous water, not a no-go area, I just wouldn't want to be hotter than that for a prolonged amount of time for safety reasons. but 60+ is definatly too high imo. get some better cooling, it's a paramount part of overclocking, the stock cooling will only get you so far.

Well if you look at this image here it shows that the stock HSF running at stock X6800 speeds (2.93GHz) hits 56c. So if Intel call that safe from running stock HSF I imagine a little higher would not hurt.

it really depends on the chips. With these newer chips, you can stand to have a higher temperature. However, its safer to stay at or below 60; 65 is pushing it. If you want a further explanation of why you should be cautious of the temperature, refer to one of the previous OCN threads about whats going on in your processor..

thank you for your advice guys.

I've tried everything:-

1. Replaced the Standard thermal paste to Arctic Silver 5, by following instructions on their site.

2. Sorted out the loose cables and bundled them together to avoid airflow blockage/problems.

3. Added an extra 12cm fan at the rear of the pc case to allow air to be expelled.

4. Adjusted the zalman CNPS9500 fan, so that it is connected directly to the motherboard and not the FAN MATE controller..this allows it to spin at upto 2700rpm, instead of the standard 2500rpm.

5. Turned down the heating in the room

6. Placed the PC Case on the floor rather than the desk as air is cooler at the bottom.

I can't think of anything else....

You can likely knock off 5-10 °C by lapping both your HS and your IHS on your CPU. See those links for some temp results I got on my q6600 and for some pics. Keep your tjunction under 65 °C (TAT, Coretemp or Rightmark) and you'll be fine.

See this thread for more in C2D temps.

i'm sorry graysky...what do you mean by lapping? is it difficult for a novice like me to do this? How do i keep my tjunction under 65 °C???
