Windows 7: Case getting hot

Case getting hot

Hi guys.

My case is getting very hot inside and has only recently started doing so.

My case is a Coolermaster Elite 334 and i have a 92mm variable fan up front and a 120mm fan on the back.

Any ideas as i am pretty new to this.

Thanks in advance.

How hot is very hot? You need a temp monitor like HWMonitor or just look in the BIOS for most temps.

How many degrees has it changed? Or are you just relying on putting your finger in an exhaust fan wake?

Have you been inside the case fiddling--particularly with your heatsink, processor, or fans?

Do you overclock?

Has your fan noise or apparent functioning changed recently?

Any new hardware?

System apparently working OK except for your concerns?

Many more details needed, particularly if it is a sudden development and not gradual.

Don't forget that a periodic vaccuming or blowout with compressed air, to shoo away the dust bunnies, is always good preventative medicine for airflow considerations. Does your case have a filter on the inlet side?

Hi guys.

Thanks for the quick reply. sorry mine wasnt as quick but hey, work calls!

To answer your questions ignatzatsonic:

I am indeed putting my finger in the exhaust fan wake.
I have only been inside the case to see what the temp was like in there (warmer)
I do not overclock.
No new hardware
System is fine apart from temp.
My temps from HWmonitor are as shown.

According to the specs on the case you can change out the 90mm front fan for a 120mm and while there remove the air filter and give it a cleaning along with blowing out the case.

Probably would not be to difficult to mod the mesh opening on the side pannel to install another 120mm fan and make sure you have the air flow coming into the case.

Hope this helps some

A few comments:

Attached is my HWMon screen. Notice that I do not show any voltages or fan speeds. I'd like to see my voltages and fan speeds, but am clueless enough that I can't figger out how to do that. Can you help me or do you simply have a more advanced version of the program?? Mine is version 1.14.0 and seems to have NO configuration options. Help? Where exactly did you get that version? Was it free?

Notice I have HD temps in my screenshot and you don't. Don't know why on that either.

On to your screenshot:

I see you have a Pentium D. Just going from memory, don't they tend to run hot?? I don't know offhand if 52 is unusual. My Core 2 Duo is always in the low 40s or lower.

I see your fans are turning pretty high (compared to my PC). Are they single speed fans or do they change speeds according to internal temps? Some fans can be adjusted to always run faster through a manual switch.

I have to believe the AUXTIN reading is bogus. How could you have any part of your PC operating at 6 (43 fahrenheit) unless you are outside??

Don't know where the SYSTIN monitor is, but that looks quite low.

ACPI: I know what the acronym means, but I don't know exactly where or what that is measuring. Appears acceptable temp.

Radeon temps appear quite low.

General opinion: Google Pentium D and find out if they are known to run hot and if 52 is excessive. There were some Pentium models that were known to be furnaces and I think it may have been the D models.

Make a spreadsheet or Word doc and monitor temps periodically so you have a baseline by date. Expect higher temps in summer if ambient temp is higher then.

Download a system utility "stress tester" type of free app that can make that Pentium D really sweat so you have an idea of how hot it can get. Google acceptable Pentium D ranges. 52 may be very acceptable and beware of relying on fingertip in a wake as an accurate indicator.

Possibly locate another temp tracking app as the 6 degree reading on that one location makes you wonder about the overall accuracy.

I notice your 12 volt line is at about 11.3. I would track that as well. That's lowish, but I think still within acceptable ranges. If it got down to say 11.0, I might worry. Maybe it is transient as those things do move around.

Help me out on where I get your version of HWMon.

Hi guys. I sometimes get allot of peeps who have a squillion fans or sometimes oversized fans and are still getting some high temp in side their cases. This can sometimes be due to a negative air flow. You might have to look at the size/design of your case and also check out if your cables are neat and tidy and not restricting your air flow.

Have a looky here .... it makes for some interesting reading
