What's Causing the Heat?

Hey guys,

I built a PC with the below specs about a year ago... but have been seeing some unexpected slow-downs lately. In another thread someone suggested it might be virus related, but after watching my comp through Core Temp, I am noticing that my PC always runs pretty hot.

Even when idle the Core temps are around 86 degrees C.

Should I be investing in an additional fan or something?

First you should see how many fans you have hooked up and then you should see what direction they're pointing in before you decide to add more. If I'm not mistaken the HAF X has mounts for 200mm fans on the top and the front and then a 120mm fan mount on the side.

HAF X Cooler Master

is that your cpu core temps?
have you got software with your motherboard to measure these temps?
what cpu cooler are you using at the moment?
i have a core I5 2500k in a coolermaster storm enforcer,my idle cpu temps are 30-35c with room temp between 20-25c...my cpu cooler is a cm hyper 212+ with a single 120mm fan

I'm just using the stock fans. I wouldn't have touched the direction they were pointin in or anything...

Yeah... Unfortunately those are my coretemps.... I'm using CoreTemp to determine this. All Core's are in the "Yellow" (High) temperatures

Just using w/e is stock with the HAF X and the CPU. Am not using any additional CPU coolers....

Darn... Okay this is good to know.

-----------------

So three questions:

1. Should I just get an additional fan?

2. Is there anyway for me to test the fans that I do have? Maybe the're not working correctly?

3. Is anything about the fans being set from BIOS? Like can I set it so they're always blowing harder?

-----

The only other relevant piece that I can think of is that the computer is lodged in between a bookshelf like cubby. There isn't much breathing room on the sides of the computer.

Thanks a lot guys!

Hm... I just used the SpeedFan software.... and it's saying none of my fans are spinning. Maybe this is just some connection got loose... Will check

i think the stock fans in your case should be fine,its a very good case the HAF X..just remove the side panel and check the fans at the front and side are blowing air into the case,and the rear fan is sucking air from the case,i use my asrock motherboard software to control my fan speeds when they are connected to the chassis fan header on my motherboard, so they are quiet at idle,i have not used the bio"s to change the fan speed,so i am unsure how to do this,if you still have very high cpu temps,i would remove the stock cpu cooler,remove the thermal paste and replace it with good quality thermal paste and refit the cpu cooler,the stock cpu cooler are not very good,but those temps still seem too high.you can also check that there is enough cool air getting to your case between your bookshelf...here is a link to the cooler i have,good luck

computer cases generally suck cool air from the front and blow hot air out the rear.

if your computer cannot exhaust that hot air it will cause the issues you are seeing.
Try running the computer out of its little cubby for a few hours and see if thats the issue. better than going out and spending money on something that may not fix the issue.

I'm betting your CPU cooler is just not working right. Maybe your thermal paste application was off, or the cooler has loosened or something. I don't see any reason not to pick up a decent low cost cooler and just replace it.

p.s. My 2500k overclocked to 4.3 ghz is currently running at 35c with one of the $60 all in one radiators. It previously idled around 37 at stock speed with stock cooler.

PCs need maintenance just like anything else. Clean it out with compressed air and do some research on airflow.

Just for the purpose of updating anyone else who might need help down the line. I ended up being able to drop my Core CPU temperature from the 86 - 98 degrees Celsius it was originally to the current 27 degrees Celsius using a couple of things.

1. Started off by just adding in a 120 mm fan (http://www.newegg.com/Product/Product.aspx?Item=N82E16835103060)... Don't think this did much. Maybe a couple of degrees.

2. Added in a 200 mm fan dropped me down I'd say a good 15 degrees... (http://www.newegg.com/Product/Product.aspx?Item=N82E16835103073)

3. Added in "Big Bertha" -- Cooler master Hyper 212 CPU Fan (http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065) as well as some new Arctic Silver Thermal Paste. Temperature now sitting in at 26 C.

The whole way through I used this figure to place the fans. http://www.coolermaster-usa.com/landing/haf912/home.php...

In any case. Thanks everyone for the help. That was a pretty neat learning experience.

Now finally onto overclocking!
