Well, as the title sums up, I am having this problem:

My CPU overheats a lot, and it's fan works around 6500RPM (making a very annoying noise).

My system is new, so there is no dust inside my computer.

Also, I'm experiencing a very bad performance with my computer. I am playing Rome Total War II all in Ultra and it lags a LOT (I think my rig should be able to play it all in extreme). My brother has a similar rig (mine has better VGA and better Processor) but his has 8gb RAM instead of 4GB and can play all set in Extreme settings with barely no problems.

My system specs are as follows:

OS: W7 64x Ultimate
BIOS: 07/12/12 v16.1
Processor: AMD Fx 8350 x8 4.0 Ghz
Ram: 4096mb
VGA: AMD Radeon HD 7970


For your reference, Here you have a pic of my SpeedTest results (by the way, I have tested many different programmes and all of them gave similar results) This are not in game results. They are with the game launcher opened (as soon as I open the game launcher, the RPM and temperature sstart to go even higher).

The sides of the computer are very hot when gaming.

I don't know what might be the problem , I am desperate.

Please, help me..

Looking forward for your reply!

Check that the CPU fan is seated correctly. Also make sure you have some fans in your case to get rid of all the heat.

Rome total war 2 is the most Un-optimized game ever. The CPU is used for a lot of the tasks that the GPU should be doing. I run it all on Extreme with the exact same specs as you. Your CPU is most likely throttling.

Thank you for your reply:)

Yes, it is seated correctly.

I indeed have in my case but they are unplugged since they didn't do much (I use to put my hand in front of them while working and I could barely feel any air coming out of them).

They sure are low quality fans.

Do you think I should plug them in order to work? Truth is I don't have any molex connector available to do so , but I could buy an other current adaptor... But they really didn't blow any air at all.

What do you mean by my CPU is throttling? that the temperature is ruining my performance?

Thank you very much for your support

Looking forward to receiving your reply.

The CPU throttling basically means that if the CPU's reaching it's thermal limit it will lower performance to be able to keep a cooler temperature.

Did you apply a pea sized bit of thermal paste onto the Cooler? If you use to much it could cause higher temperatures.

Also, make sure you have a fan blowing in cool air and at the top of the case have one pushing hot air out. If they aren't dong much I suggest you go buy two quality fans. This might sound silly, but are the CPU fans running?

Oh, I see. I hope thats the problem. I was getting frustrated at the fact that I can't play this game on max with a "powerful" rig.

Yes, I added just a little bit to what it already had (I changed it recently, so in order to be sure, added that little bit).

Do you think that the fact I have those side coolers unplugged is the reason for this high temperature?

This is a pic. of my case

Can I replace those 2 coolers on the side of the case, with two quality ones?

Yes, the CPU fan is running, at an stonishing 6880 RPM. Reason for which it makes such an annoying noise.

Are you using the stock AMD cooler on the FX 8350?I suggest you try changing to an aftermarket cooler (air cooler/liquid cooler) for the CPU and some more fans in your case for proper ventilation.62 Degree Celsius is the 'safe' maximum temperature for this CPU (though I don't remember AMD officially announcing it) and assuming that I am correctly reading the temps in Speedfan (I don't use it),it is already over that limit due to which it is throttling.What's your motherboard,by the way?Are all power saving functions enabled?Although for maxing out games,you would get better results with the power saving functions set to off.
Hope this helps.:)
Edit: DON'T try switching off the power saving functions to off with your stock cooler.:no:

Which power saving functions are you speaking of? I have never heard of them, at least on desktop computers.

Mother is a ASUS M5A78L-LE.

Yes, I am using the cooler that I received from the original box.

Thank you for your help, and i'll be looking forward to your reply! :)

Well,my ASRock motherboard has power saving functions like AMD Cool 'n' Quiet,Automatic throttling management etc.I looked up your motherboard too on-
http://www.asus.com/Motherboards/M5A78L_LE/
and I noticed ASUS 'EPU'.Many motherboards have power saving functions which may be enabled/disabled by default and are named differently according to your motherboard's manufacturer.Check in your BIOS if they are set to 'On' ,but only after checking it's description in your BIOS or on Google.Do NOT turn them off without installing a better cooler.:no:
First,check if all power saving functions are on in BIOS after reading up on them.
Two,read the FAQ section in this thread to check if you need a cooler upgrade.

http://www.tomshardware.com/forum/277130-29-read-first-watercooling-sticky

Do not think straightaway that 'I need to install a water cooler'.A decent air cooler will do the job,but remember,the stock cooler will NOT suffice.
Third,monitor temps while checking your airflow.If they are significantly lower,try changing the position of fans in the case.Then,when you hit the lowest temps after fan adjustment,go for a good cooler like Cooler Master Hyper 212 Evo.
Fourth,apply thermal paste properly after cleaning off the old thermal paste (My liquid cooler came with pre-applied paste) and install your air cooler.Keep in mind,every time you remove/reseat the cooler,fresh thermal paste needs to be applied so keep some in stock.It's a good idea to put a pea-sized amount of paste,but too much paste may be bad.
Fifth,monitor load temps (should be below 62 Degree Celsius for core temps) and if all goes well,enjoy! :)
Hope this helps.:)

Thank you for your help and support.

I made some enhancements on my CASE coollers and now the temperature goes very well. (While playing Rome Total war II all on extreme 67-68°C) is this okay?

I also erased EPU when I got this computer, is that wrong? It may be the reason for which my CPU FAN has such a high RPM.

Moreover, I bought a 4gb DDR3 HyperX RAM so I no longer have performance problems.

Is that temperature okay? Do you recommend updating Case coollers? as well as CPU FAN?

Thank you!

No problem. :) However,you need to know that whatever be the game,keep the core temperatures below 62 Degree Celsius.I am not sure whether there was any official figure from AMD but take a look at this thread here -

http://www.tomshardware.com/forum/id-1727374/official-8350-temps.html

Now,which temps are you monitoring-core temps or socket temps?Sorry for the question,but I do not use Speedfan (yet) so I honestly don't know which temperature it reports....Does your PC restart/Blue-screen/freeze while playing games?

To answer your second question,erasing EPU is not a bad thing if you feel it is slowing down your system,but if you want to keep things cool without an aftermarket cooler,I would suggest re-installing it ,if possible....However,keep in mind that I am being a bit cautious here,because I do not know how EPU works on Asus Motherboards....You could Google /start a new thread about it.I disabled my motherboard's power saving functions because my CPU was constantly dropping it's multiplier to 7 from 21,when I was using air cooling.So,games used to stutter a bit...that is why first thing I did,when I got liquid cooling,was to disable them and switch to a constant multiplier speed in BIOS....I did not remove them,so that if anything went wrong,I could turn them back on.;) I have read that the stock cooler from AMD does sound annoying ,possibly due to it's high RPM setting.I straightaway used an aftermarket cooler,because I had read that the stock cooler was not enough for this processor....

In the end,my recommendation would be not to ''update'' the case coolers,but ''re-position'' them for better airflow in your case,after getting a better CPU cooler.Lots of people have the Cooler Master Hyper 212 Evo and are pretty satisfied with it. :) And just in case you need help with how airflow works,just check the direction of arrows etched on your case fans and position them accordingly....It helps a lot in bringing down temperatures.....:)
