if those temps are accurate they are way to high for stock....you need to make sure the cooler is making good contact. I would completely remove it and start over. Did you make sure the fan was working on the heatsink?
Yes, temps too high. if the fan isn't workin, the mobo should just shut down unless you disabled that control.
Unless you left the plastic cover on the heatsink when you installed it, or removed the pre-applied thermal paste, the heatsink is not properly seated on the mobo.
You need to remove the mobo and make sure that each of the four legs shows two white pins poking through the back of the mobo, with a black pin in between them. And that the barbs on the white pins grasp the back of the mobo, locking that leg in place.
Core i and Core 2 processors have 2 different types of temperature sensors; a CPU case (not computer case) Thermal Diode centered under the Cores, and Digital Thermal Sensors located on each Core. The case Thermal Diode measures Tcase (Temperature case), which is CPU temperature, and the Digital Thermal Sensors measure Tjunction (Temperature junction), which is Core temperature. Since these sensors measure 2 distinct thermal levels, there is a 5c temperature difference between them, which is Tcase to Tjunction Gradient. Core i7’s / i5’s and Core 2 Quad’s have 1 Tcase and 4 Tjunction sensors, while Core 2 Duo's have 1 Tcase and 2 Tjunction sensors ...
... The monitoring utilities provided by motherboard manufacturers monitor CPU temperature, while some popular freeware utilities monitor Core temperatures ... Real Temp ... is recommended for users interested in monitoring Core temperatures only ... SpeedFan monitors Tcase (CPU temperature) andTjunction (Core temperature) ...
The thermal specification which is shown in Intel's Processor Spec Finder is Tcase Max (CPU) NOT Tjunction (Core), which is a very common misconception among most enthusiasts. Since there's a 5c gradient between the CPU sensor and the Core sensors, (shown in the following Intel document) - http://arxiv.org/ftp/arxiv/papers/0709/0709.1861.pdf - just add 5c to the value shown in the Spec Finder to find the corresponding Core temperature, which is 78c for the Core i5 750.
Intel's second and frequently misunderstood thermal specification, Tjunction Max, (100c for all Core i variants) applies to overtemp protection such as Throttle and Shutdown, so you don't toast your transistors. As such, any i5 Core temperatures which exceed 78c should be considered "overtemp". Further, when specifications are exceeded, then premature processor degradation (longevity) becomes a factor that should be considered, which is explained in the following AnandTech article - http://anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3...
I can confirm that the temps on this chip are very high. and I've also re-pasted. After playing GTA for 5 mis with a stock cooler the temps hit 83c so I shut the game down. It's housed in a new CM 690 with 5 x 120mm fans and a mobo temp of 27c.
I ordered a Zalman CNPS10X to go with my Asus P7P55D Pro, but the 1156 bracket that Zalman made doesn't fit the mobo, so I RMA'd it. I'm less than impressed with them and the cooling manufacturers in general as they are dragging their feet in releasing new coolers and brackets. So I have a shiny new PC bought for gaming which I can do nothing with apart from basic tasks.
On the review in the link they comment how small and thin the stock cooler is.
Don't use "Blend" as it's a memory test that cycles at less than 100% workload during certain test segments, which yields fluctuating temperatures. Small FFT's instead is a steady-state 100% workload that's ideal for processor thermal testing, which yields steady-state temperatures. Thermal saturation is typically reached within 7 to 8 minutes, so a 10 minute test is adequate.
Currently I have the standard Antec 300 case... I know the above poster mentioned a better case...
I can currently reach a 150x20 (21 turbo'd) overclock with max temps at 76 C...
Would it be better to buy another fan for intake on the front of the case or an aftermarket cooler for the CPU to push this OC further?
Looking at Newegg, the standard Antec 300 comes with two front intake, one top exhaust, and one rear exhaust fan. That's plenty. Make sure your wiring does not restrict air flow any more than necessary, and that's pretty much the best that case is going to do.
If you do not have those 4 fans installed, by all means install them.
If you are going to do *any* 24/7 OC, you should install a high-performing aftermarket cooler.
Unfortunately Intel have decided that it would be a good idea to have another change in HSF mounting hole positions, which Asus can do nothing about. So current 1366 coolers and even 775 coolers will be incompatible, so it really is a completely new setup and we really have to ask, why!? It is possible that Intel have improved the mounting system on their retail coolers for the lower end i5 and i7 models which requires different hole locations. We do however feel that its much more likely that they’ve saved money by producing cheaper HSFs for a range of processors where the heat output will be lower than the current Bloomfield i7s, keeping the more expensive high end HSFs for the higher end chips, but this of course is all speculation and I expect we will never know what Intel were thinking (or not) when they made this decision. What this means for most of us is that we can’t use the current crop of aftermarket i7 coolers designed for 1366 motherboards, many of which are frankly excellent. Hopefully the hard done by HSF manufacturers are on to this issue already and there will be 1156 coolers & adapter kits for some of the great 1366 coolers already on the market, before the release of Intel’s new 1156 boards and CPUs.
There IS something ASUS can do about it: they can manufacture
2 sets of holes, as they have done with other motherboards
like the P6T:
