CPU running hot and heavy load!

Hi all,

Never really posted here before but know most people are good on here for advice.

I recently went back to playing World of Warcraft on my PC, and decided that I needed to get a new GPU as my old one had a few broken fins on the fan. I replaced it with an R9 270X, it was working great for a couple of weeks and was running a lot quieter than my old card.

However after a few weeks I had been playing on the morning, went out for the afternoon and came back on the evening and attempted to turn my computer on.

Upon turning it on it wouldn't boot and was stuck on the black screen just before the windows logo. I tried to restart it and after a few goes got a message saying a disc read error has occurred.

The same time this was going on the CPU cooler fan sounded like a helicopter and the heatsink was red hot. I had a look at the fan and the CPU cooler pretty much fell off, I looked at the cooling paste and it was rock solid and pretty much peeled off.

I put my old GPU back in and was advised to put some tin foil folded into a square under just to see if it would boot (it didn't). The next day I thought I'd have a quick look and see if it would turn on and it did. Booted up completely fine but still sounded horrific. As such I got some new cooling paste and applied it to my CPU and cooler as advised by the packaging.

For another week or so the computer was completely fine and was running even quieter and cooler than before. I popped my new GPU back in and it was working great. Now a few days ago the same hang up happened and it wouldn't start, with the CPU fan sounding awful once again.

I had been having some problems with windows updates (I'm running windows 10) but I've now fixed them through a refresh and can't see this being the problem?

However it is still running very loud and very hot (hitting up to 50°) even when idle. I have an 8 core AMD processor and the load on the first processor, according to core temp, is getting up to 90% and the other 3 or 4 below that up to 70%, again even when idle. I can't work out what the problem is at all, is there anything I can do?

Any help would be appreciated!

Do you have the motherboard model? And if you are going to play games never use the stock fan they are always bad for it. Yes if the heatsink and fan are not working correctly your CPU would overheat in a matter of seconds forcing a shutdown.

My recommendations before you do anything too drastic, update your BIOS, clean your fans, and check and double check that all of your power cables (including the fans) are correctly set-up.

The issue could be a number of things, the more probable being airflow. Is the new GPU blocking your CPU airflow? The new GPU might be more efficiently removing air from the GPU and releasing it into the case making your CPU warmer. What PSU are you using? You might be supplying too much to either the CPU or GPU or not enough. If your thermal paste solidifies best course of action is rmoving the CPU and carefully removing the paste with Isopropyl Alcohol, and replacing it.

Hi thanks for the reply.

My PSU is a corsair tx650w, the GPU is positioned in the same place as my previous card. Which is about two inches below my CPU the CPU cooler is horizontal blowing air forwards and the GPU is vertical and blowing air down (hope that makes sense).

The GPU does have 3 fans on it as well, could that be the problem?

I've already removed and replaced my paste so hopefully that's not the issue. The CPU was still getting hot and loud with old GPU in as well. Is there any way of finding out if something is getting the wrong power levels?

Thanks again

Your GPU is quality so that won't be the issue. Does your case have an exhaust fan on the rear or front? You should always have the fan on your heatsink pointed toward the exhaust. Make sure you have your bios updated. If your CPU cooler is still sounding like a helicopter often times it just needs to be cleaned (I recommend dusting everything with canned air (make sure you use it in bursts or the compressed air will condense into water)) That is the extent with CPU fan knowledge I have. If it were me I would just upgrade to a closed loop water cooler or if you are confident in your abilities open.

Good luck, Owen

Cheers Owen,

I have two fans pulling in at the front end (one on the side and one on the front) then two at the back (one directly above my CPU cooler and another on the back at the top).

CPU is an AMD FX-8350 black edition I believe! Never really updated the BIOS before so how's the best way to go about that?

How to update: http://www.pcworld.com/article/187437/how_to_update_your_bios.html

So is your mobo compatible with an 8-core? I somehow managed to miss that reading through it, if its not compatible than your mobo is gonna try and throttle the hell out of your CPU as it is reading it as a 4-core most likely. Which basically means your gonna run really slow and really hot, with your cpu fan running constant. Is your CPU cooler stock or aftermarket? I have a feeling it has to do either with your mobo or you have a broken fan.

I've had the motherboard and processor for 2 years without any problems, even ran some higher end games on it going back a while with no problems.

The motherboard and processor were bought preinstalled from ebuyer as well so would hope that wasn't the issue.

Could be the fan as it is the stock one. But would that cause the computer not to boot?
