Is the CPU too hot?

H

happymac.support

Forget PC Probe numbers. I do not mean a chipset temp, i
mean the actual temperatures of ALL parts in the system.
You can use a thermometer of some sort or touch-test with
your finger, or go overkill on airflow to be sure everything
is beyond a reasonable margin.

That the CPU is so hot is a sign "something" is wrong. Fix
that something, instead of looking at software.


Thanks. Does anyone know what I should do? I felt inside that case and
its just as hot as any other computer, around 35 degrees. How do I
increase airflow? I've made sure that the computer has enough room on
the sides for airflow but I dont know what else to do.

OK, This is crazy. I checked the temperature using AIDA 32 (an older
version of EVEREST) and guess what? When the Computer was idle for the
CPU, while PC Probe showed 75 degrees, EVEREST showed 45 degrees!!!!
The motherboard temp stayed the same but there was a amazing
difference with AIDA. What should I trust, AIDA or PC Probe?

Your finger.If you can keep it at the site without
discomfort,Everest is right.
Else Aida is right. :) :)

Never use another software not specifically designed to read
your particular motherboard's temps, unless it very clearly
has a setting, known to work properly, specifying that same
board.

The right place to check the temp is the bios
health/hardware monitor page. On that page the temp will be
a few degrees warmer than sitting at idle while running an
ACPI enabled OS, and a few degrees cooler than running at
full load.

I checked the BIOS page. Unfortunately, it shows the same readings as
PC Probe--around 70 at idle. Any suggestions on what I can do? Maybe a
fan is failing, as I said in one of my previous posts:
i have noticed something though. Before from
when I got the sytem to 3 months ago there was a sound of something (i
am assuming its a fan) that revved up and down. Now, the fan noise is
consistent and stays the same. Maybe, just maybe the system was a bit
louder before.

I honestly dont know. What do you think? I checked on the ASUS page
for my motherboard and there is nothing about cooling issues or
anything. Oh, by the way, I found out the number of fans I have. here
is the info:

1) Power Supply Fan
2) GPU Fan (on the graphics card)
3) CPU Fan @ around 4115RPM
4) Case Fan (attached on the inside of the case)

No idea if thats enough. As far as I can tell, all the ones listed
here are spinning. there is air coming out of the Power supply fan,
the GPU fan is spinning, the Case Fan I can see is spinning, and
obviously the CPU fan is going too.

Determine which subsystem is suboptimal.
It's not hard, look over all aspects of the system, which is
interfering with optimal cooling? The only case where there
is something that wouldn't be obvious is if you didn't
realize the quality of heatsink needed or that 'sink wasn't
sitting on the CPU good, in which case you'd remove it,
clean off thermal interface material, apply tiny bit of
heatsink grease and reattach.

Maybe a
fan is failing, as I said in one of my previous posts:

Well are any spinning at an especially low(er) speed or not?
That should be pretty easy to determine just by looking at
them, if not an RPM readout.

I honestly dont know. What do you think?

That you have not adequately described exactly what all your
system's cooling subsystems are like. We can't see the
system.

Describe in detail what case, what fans, where they are
mounted, what obstructions there are to each compared to
having only a large open hole. This includes the case front
bezel.

Describe room ambient temp during these temp readings.

In short, tell us about your system and environment.
Something about it is different. Only by thorough
description will that become evident.

The room temperature at the time of these reading was 19C-20C (the
room temperature is controlled by a programmable thermostat). The

noticed that there is (I think........) a sound of a wire or

temperature readings


Your links are not working. Primarily the goal was to
determine what % of the fan intake and exhaust on both sides
of the fan frame, are blocked by anything.

You might take off the case side panel and point a desk fan
at the system to see if the temp then drops by a significant
amount, if it does that is indication enough that the case
airflow needs improved. If it does not improve
significantly, it is time to take off heatsink and remount
it as mentioned below.

Here are the details on the case and fans:

Case: 17 inch tower case "SPORT" brand (I think its a cheap case)
Power Supply: 400W


Do you see that telling us this is not necessarily enough,
we would need some good pictures... they need not be of your
particular case, just the same case from anywhere online
unless you have modified yours to differ from the way it
shipped.


1) Case Fan
Type: FAN DC 12V (with red, green and blue LEDs)
Location: On the middle of the left side of the case. Its attached
from the inside. The fan is about 2 inches (not sure, check pictures).
Wire mesh covering outside the fan,


As mentioned above, the pictures are not working, only some
gambling site page appears.

The goal in asking for description was one of determing how
much restruction there is to airflow. A good picture may
show that, but only telling us there is wire mesh without
any idea how much it is restricting airflow, does little
good. Wire mesh could block 90% of the airflow, for all we
know, particularly if fine enough that it traps dust and the
environment has a fair amount of dust to trap... the system
can effectively become the room air cleaner... or not, it is
a shame the picture links aren't working.

That side fan should be an intake. If you think the mesh is
impeding airflow too much, try removing the mesh.

2) CPU Fan
Type: Intel stock
Location: on the cpu (obvious) - check pictures

If you think it is not mounted good, you might remount it...
of course you will then need to clean off the original
thermal material and apply a tiny bit of grease. If all
else fails, remount it anyway, just so you know it is
mounted good.

3) GPU Fan
Type: graphics card fan
Location: MSI Card (chipset: ATI RADEON X1300 PRO)

4) Power Supply Fan
Type: power supply fan
Location: inside power supply (covered with a wire mesh, see pictures)

There should be no mesh on the PSU fan. It needs all the
airflow it can reasonably get. If your mesh is also
preventing wires from getting into the fan blade path,
consider a rounded wire (usually chromed) fan guard instead.

The room temperature at the time of these reading was 19C-20C (the
room temperature is controlled by a programmable thermostat). The
above described fans are the cooling system this machine has. I also
noticed that there is (I think........) a sound of a wire or

?? You might want to check on that, I wonder why you are

already.

I can't see the finer details, is there ample air intake?
If there is not, flipping the side fan will have more of a
benefit but you ought to also find a way to get more front
intake to cool the HDDs better.

I was also interested in the inside front wall of the case,
directly behind the "front of case" shots you linked above,
since there is a double wall of plastic then metal, there is
a double opportunity for the case to impede airflow.

Some of the pictures are a bit too close and too fuzzy to
get a good idea, but it might also be the dark colors of the
case.


It looks a little bit like it's really clogged with dust?
That might be the problem.

What about a rear case exhaust fan, below the PSU exhaust
fan? That is recommended by Intel & AMD... and the case
should have one, ideally.

Overall I would say the case "might" not have very good
front intake, but mostly it looks like dust in the heatsink
is to blame.

What about a rear case exhaust fan, below the PSU exhaust
fan? That is recommended by Intel & AMD... and the case
should have one, ideally.

Overall I would say the case "might" not have very good
front intake, but mostly it looks like dust in the heatsink
is to blame.


OK, as a first step, this is what I will do over the weekend: First, I
will open up the case, bundle up the wires a little more neatly, clean
out all the dust, and possibly, install the side fan the correct way.
After, without closing the case I will run the computer to see if the
temperatures are reduced. If they are, I will see if I get the same
results with the side of the case closed. Will it help? Also, I
checked and there is no rear exhaust fan. If cleaning everything
doesn't help, I guess I will have to add some more fans and maybe a
better cooler (Zalman it seems is good) for the CPU. I will report to
you everything I find on Monday (or maybe earlier). thanks for the
help, everyone (especially kony)

Bundling wires would be mostly a vanity thing, since you
have the window, as it is not a serious impact on cooling,
nor are parallel ATA cables as some in the past have falsely
assumed (unless they're literally draped overtop of a
heatsink).

Dust, definitely clean it out. Cleaning out the CPU 'sink
is priority #1. If it is as bad as the picture suggested,
that may completely resolve the problem, but even if it
does, I would still consider flipping the side panel fan
around if you feel there is enough front intake to keep the
HDD(s) cool enough, since flipping that fan will impact the
airflow past the drive rack.

A good (better) heatsink would keep the CPU cooler, but the
retail 'sink is sufficient in keeping the CPU significantly
cooler than it is, especially at the (low) room temps you
reported. Replacing the heatsink would be better tailored
to reducing noise, if you felt the retail heatsink was too
loud.

I dont think a front intake fan because at the current time, as you
can see in the SpeedFan readings, the HDD is cooler than average, so I
dont think its a problem but I will bundle wires and clean out the
sink as you suggested. Will report back once I have done it.

They did not work previously doing as you suggested but the
following links do work.




The side fan is installed backwards, BUT while it might help
to do that, I don't expect it to help enough.


I can't see the finer details, is there ample air intake?
If there is not, flipping the side fan will have more of a
benefit but you ought to also find a way to get more front
intake to cool the HDDs better.

I was also interested in the inside front wall of the case,
directly behind the "front of case" shots you linked above,
since there is a double wall of plastic then metal, there is
a double opportunity for the case to impede airflow.

Some of the pictures are a bit too close and too fuzzy to
get a good idea, but it might also be the dark colors of the
case.

Oh and another question, if I remove the heat sink, when I reattach
it will I have to apply another coat of thermal compound, or can I
just attach it normally without doing anything?

Thanks

That may be true, but a HDD temp reading is only of one
place on the HDD, not the rest of it.
