I have been wondering about the behaviour of my core temperatures since almost two years. I have a I7-950 (see signature) on an Asus PT6 motherboard using a Thermalright 12UE cooler, recently equipped with a bequiet SilentWings fan (120mm, 1350 rpm) within a Lianli A70 case (plenty of open space inside).Overclocking settings: 195x21, Vcore 1.275 V, VQPI 1.325 VI am performing stability tests with OCCT (1hr auto) with the following typical results:Room temp: 26 C (we have the warmest Easter since the Big Bang)Core temp idle: 52 C (GPU temp during idle period: 40 C)After 5 seconds of full OCCT load: 68 C – a 16 degrees jumpAfter10 minutes the core temp settles around 84 C.Equally, the RealTemp sensor test shows a 17 degree C movement with this brief stress test.My question is: could the initial rapid temperature rise (16 C in 5 seconds) be an indication of a poor thermal bond between CPU and cooler. As I did not build the rig myself, I would hesitate to be taking it apart unnecessarily.Boudewijn

The initial temperature rise is perfectly normal. What concerns me the most is your max temperature (I prefer to stay below 70 to 75 while stress testing). You need a faster fan - something closer to 1800 - 2000 rpm instead. There's a lot of really good fans in the 1800rpm range out there. I'm fairly partial to the Scythe Gentle Typhoon AP-15. But they are pricey and they're often difficult to find in stock.You might also look at the AeroCool Shark 120, Scythe S-Flex, and Noiseblocker fans.

Your temp are way to high for your overclocked, here I have a 980X and the temp never went over 69C at 4.51GHz..reset the CPU cooler with better paste or get a better one, I'm using the NH-D14.

Thanks a lot guys for your feedback.I will reinforce my cooling system. In the meantime I have reduced Vcore to 1.225 and VQPI to 1.27 V giving a stable 3.95 GHz OC. Temperatures are down by some 8 degrees, with FSX staying below 70.Thanks again,Boudewijn

.. you might try 20 x 200 for 4.0 gig. I ran this way with a Muggen2 for half a year, with 72-3 as tops using IBT and LinX. Honestly, though - water is the only answer for good FSX performance.

I can recomment the COOLIT A.L.C. waterblock, very cheap, easy to install, silent and keeps my 2600K at 55 degrees Celsius at 4,2

Your temps are right where I'd expect them to be given your high ambient temperature, older heatsink with low speed fan, and what may be a general lack of system airflow. There are a few solutions available, several of which have been mentioned, though I would like to add that it would be a good idea to add some fans to your case if at all possible.
