Hi guys I just finished one of my builds and this one is the gaming one. I just looked at the temperature in the MSI bios and it states that my CPU is hoovering around 50 degrees celcius. I have more than enough super fast airflow fans in my case blowing at, on top, and out the haf 922 case. I just cant seem to know why it is so hot? Can anyone help? Am I doing something wrong?

Listing your system specs would help along with posting a screenshot of your temps, voltage, etc.

I cant take a screen shot because I am using a laptop and at the moment I turned off my rig so that nothing horrible will go wrong.

I'll see if I could find a camera.

50 is high for idle. It should be around 32 with the stock HS and fan. But thats not whats important. Whats important is what it is underload. I would reseat the HS and fan after cleaning all the thermal compound and applying new. google it or go to Artic Silver web sit for detailed instructions.

I tried everything. Even worse the one of the stock cooler's pins won't lock in tight on the motherboard. What should I do. The cpu is still idling at 50 degrees celcius just in the boot menu. The only thing I did was add a new CPU and MOBO to an existing SSD that already has OS installed from a previous rig. I also have a couple HDD that are plugged in from my other rig; is this causing the super hot temperature?

Its the pin thats causing the problem. Intel's stock coolers are a little tricky. Mount the cooler when the motherboard is out of the case then you dont have to push down so hard. The trick is the top of the pin should be turned in the opposite direction of the arrow to install. Lock down the corners in a cris cross pattern Read the instructons. To remove you turn in the direction of the arrow.

About your drives. No there not causing the problem. But you need to format the SSD and reinstall if you change the motherboard to different type

Can i just ask a quick question in here as it's related? I am just wondering which number do i look at on the mobo bios for my CPU temp. Is it the Fahrenheit or the Celsius?

Well like I stated. The i5 Idle about 28c to 35c but its the heat under load thats important. Stock mine was 32c and 61c under a load. Tested with prime95 running 100% on all cores

Doesn't BIOS put the CPU under some load which can cause the temperature increase while being viewed in BIOS?

Ok, well I've been fiddling with that 4th pin of the cpu fan, trying to nudge it to lock to the motherboard; however it just seems that it is not tight enough. I wouldn't say it is super loose, but if I was to put some force just pulling on the lever the pin will come out. The other three pins seems to be fine, just this 4th one doesn't seem to be tightening. I would force it down even more hard but I rather just ask you guys if I should buy a cheap CPU fan and apply some cheap coating on it again. Will this solve the problem?
Could it be that I didn't place the CPU itself correctly?

Thanks

There are cheap options which do not use push pins.
The CPU coolers like what Jetster and I have are cheap and easy to install, although initially you do need to take out the motherboard to attach an aftermarket back plate which is supplied with both coolers.
Not too sure if my cooler is available anymore though.
Might have been replaced by the EVO.

So the problem with the high temperature (50 celcius) is because of that 1 loose pin(But it only goes loose when I pull it out with a bit of force)? So if that is the problem I guess I rather spend about 20 dollars to get a decent CPU fan and some new liquid thing right? I just finished my other build which is an i5 750, 8gb Memory, Win 7, Gigabyte P55 USB3, ATI 5670 without a hitch. This build has only one small fan, yet everything is super cool. I even used eyefinity to put some load on the GPU yet the CPU is still under 35 degrees celcius. What am I doing wrong with this build?

Jetser: I think that the pins are screwed up on the CPU fan. I tried turning to open yet it just locks.

I can not say if the temperature reading is a direct result of the CPU cooler possibily not making proper contact or just CPU load in BIOS.

I would either make sure the CPU cooler is locked down firmly or look for another CPU cooler for peace of mind.

Would a 25 dollar CPU cooler be good enough?

I personally do not have any suggestions for aftermarket CPU coolers at $25 US which are capable of cooling an i5 2500.

They are out there though.

First, in BIOS the CPU shows higher temp than idle, probably the clocks are set at default 3300MHz so 50C is not so dramatic for stock cooler. You should check with realtemp what's in idle - 1600MHz - and under heavy load - turbo. Anyway, a Cooler Master 212+ would be great for little money.

This is the CPU cooler I have and is going for $29 USD.
COOLER MASTER Hyper 212 Plus RR-B10-212P-G1 "Heatp...

Does a good job, especially for the price and also leave you worry free of those stupid push pins.

As crap Daddy verifies what I have said, the temperatures in BIOS are showing the CPU under some load which is what I thought does happen while in BIOS.

So once you get into windows and the CPU is at idle state the temperature will drop.

But still the CPU cooler sounds like it does not attach properly for whatever reason.

How do you check the clocks? I've been searching everywhere in the bios trying to find the voltage of the CPU, and the mhz. What name is it under?

How do you see CPU temp in windows? I thought you could only see it in the Bios?

When I look at CPU temp in bios in my other rig, it idles around 35 celcius.
