I have an Intel Core i5 running at 2.8GHz and i was looking into the temperatures at which processors should be running at and decided to check in the BIOS at what temperture my CPU was at. The temperture shown was 72C and this was just when the computers is running without doing much maybe browsing the web and not under any load what so ever. I'm using the stock fan and cooler that came with the CPU. Can anyone tell me if this is normal or should i be buying a more powerful CPU fan & cooler?
Since you did not state the specific I5 processor I'm basing my answer on the I5-2500 (http://ark.intel.com/products/52209?wapkw=(I5-2500). The case temp is 72.6 C. So the 72 value that you provided is too high. You also did not state what software (I have assumed this since you mentioned that it is running idle even when browsing the net) did you use in obtaining the temp value. Your bios (I'm assuming Intel mb) has a monitoring menu that will show you the processor thermal margin. So you can check that value of 72 to the one provided in the bios.
Should you be buying a powerful cooler fan? Not yet, check your system first because it seems that something is wrong.
I'm using an intel i5 760 and i simply restarted my computer and went into the BIOS and check my PC health and under CPU Temp it was at 72C and i was only using my PC for browing the web i.e. watching YouTube videos.
According to this link (http://ark.intel.com/products/48496?wapkw=(i5-760) the case temp rating of your processor is 72.7C. Having a bios value of 72C is quite high. Check how you mount the processor and heatsink assembly. Did you apply any thermal paste? Is the heatsink properly seated? etc. Also check if vents in the computer case are not block? Does your computer case have extra fans installed?
Viewing YouTube videos can also raise the CPU temperature in general. But not that high though. How did you monitor this temperature? Did you use a third party software or just the process monitor of windows?
I checked the processor last night and im sure that to heat sink and fan were installed properly but i think the problem is the thermal compound some of it is missing. I was going to buy a new heat sink and fan along with some Artic Silver 5 thermal compound but i wanted to find out if the heat of my processor was to high in the 1st place before i spent some money. Also my case is well ventilated with 2 large fans one at the back and one near the hard drive.
I checked the temperature last night again and with the processor being idle it was at 52C im sure im correct in saying this is also a high number for an idle processor.
I think im going to invest in buying some new thermal compund and heat sink along with a fan.
You have to apply the thermal paste again. Before applying a new one remove or clean the surface first then apply a thin layer of paste. It must be spread out evenly on the surface of the processor. With the stock fan you should be getting a reading of 30 - 40C using a third party software.
Core i5 760 w/box cooler. Software: AIDA64 and a video converter w/multicore support. Temperatures are in celsius scale.
According to specs max Tcase = 72.7 (and for cores it should be around 82)
Tcase = 50 while idle, 72 (cores up to 82) under 100% load in 10 min.
After cleaning and oiling the fan (not necessary), changing thermal paste:
Tcase = 30-40 while idle, up to 65 (cores up to 76) under 100% load (all 4 cores, time - >1 hour)
Don't use too much paste. Clean CPU and cooler (be gentle - scratches are bad, I've used cotton buds), then apply some paste to the center of CPU, place cooler. Wait for 5-10 min and remove cooler to ensure there's right amount of thermal paste. Remove excess paste from the sides of CPU (or add - if there's not enough on top) and install cooler. Done.
Hope, this helps someone.
Hello all, I have an Intel Core I5 CPU M520@2.40GHZ running on Windows 7 Professional 64bit.
My PC is almost 3 years now.It started making a loud noise of fan (I guess) and blows a very hot air from the left side bottom of my laptop. I used Core Temp software to check the processor temperature and it shows 55 to 67 'C and sometimes it boost up to 80 degrees. 80degrees is when hot air blows up. Do I have to repair or replace any hardware part? Need some expert advice. Thanks.
In general, processor temperature issues are usually caused by improper fan/heatsink integration or its failure. For a desktop system you may want to remove the heatsink, inspect its pins just to make sure they are not broken or bent and integrate it again applying new thermal compound if needed. When properly installed, the heatsink should not wiggle or shake if you attempt to move it; the pins should not come up if you try to pull them up.
We suggest cleaning the fan and make sure there are no obstructions or noises. The fan should be connected to the motherboard’s CPU fan header. Please refer to the following links:
You may also reset the BIOS in your motherboard as an incorrect setting or overclocking the CPU or memory may cause the processor to overheat. The processor should be tested with the default settings but keep in mind other settings may be reset as well affecting the operating system. For this step, please refer to your motherboard owner’s manual or contact their support line.
Finally, monitor the temperature from the BIOS or using the Intel® Processor Diagnostic Tool available in the link below. We cannot guarantee that other monitoring software tools will provide a correct temperature reading.
JJA, a laptop system may require professional maintenance to the fan and air duct as well as thermal paste replacement.
