No, the Power Supply fan location is not the problem.
You can do a simple test of how hot the inside of the
case is (with the case cover closed and the CPU at idle)
the air coming of the rear power supply fan should feel
cool. The rear case fan air should also feel cool.
When you run Prime95 you should notice warm (not hot)
air from the power supply fan. But with a 750W unit you
should not be running anywhere near it's rated power so
the exhaust air should be relatively cool most of the time.
One thing you can check is air flow thru the case, if there
is not enough air flow things could get warm inside.
What is the make and model of your case?
How many and what type of case fans do your have.
(and where are they located)
Are you using dual video cards?
How many hard drives.

I got a reply from them, here's what he said
[your heatsink was properly installed as I did it and it was
done as it should be.
That temperature you said is in the normal operating range and will go
up under
a load as that is normal and still within the limits. Note: CPU's
don't burn up until the 80-85-90 mark so your's is well below this.
We can do whatever you want done but its really not worth the cost
to(in my professional opinion).]
I just started the PC up after being off most of the night, the temp is
40c, MB 34c. I have a new power supply, 750 watt, now the fan for it
is below the unit right above the CPU, would that cause the higher
temps? Could I flip the unit upside down to have the fan facing the top
of the case?
Debbie
You're welcome.
Adding extra case fans will not help the CPU problem.
It may keep your hard drives and Video card a tad cooler.
Hey if they messed it up and it was work they performed
recently you should not have to pay them twice for what
should have been done correctly in the first place.
Word of warning, if they say the heatsink wasn't fully
seated/locked down/loose or words to that effect and all
they had to do was make a small adjustment, don't take
the PC back, make them set it run in the shop while you
are there and then run Prime95. I say this because if it
was not seated properly in the first place the thermal
compound may no longer be 100% effective.
Let me know how you made out after you get the
unit back and make certain they didn't undo all that
work you did to get the processor running at the
proper speed. Down clocking (running the processor
slower than it's rated speed) is one way to make it
look like the CPU temperature is cooler!

Thanks a bunch for the info. You know I really appreciate all the
help you are giving me. I can email my tech shop, and ask them about
that. I bet they must have done something wrong, because they said my
temps should be lower. I can't add anymore fans on this
case........lol
Debbie
If you going to take it to the shop,
tell them "Before" you drop the PC off at their shop
that you want the processor and heatsink cleaned by
using Arcti Clean #1 and #2
http://www.arcticsilver.com/arcticlean.htm
Then to use Arctic "Ceramique" as the thermal paste/compound.
http://www.arcticsilver.com/ceramique.htm
If they never heard of Arctic brand then find another shop.
Do not settle for Arctic Silver, it's a good product but if they
are sloppy in applying it you may have worse problems.
"Ceramique" on the other hand is "neither electrically conductive
nor capacitive"
and a little too much on the heatsink is not a problem.
Applying too much Arctic Silver could be a problem. That plus
Ceramique's other benefits make it the best choice.

I might have to take it back over to the computer shop. I hate it
though because I'll get charged another $49, they have to take the
motherboard out to do it. I bet they didn't clean the old stuff off
too well. The one guy there said I should be in the 30's with the
temps, I have never been in the 30s with the temps. The new fan I'm
getting is a case fan to replace the one I have in the back.
Debbie
Based on the review by Frostytech you definitely
have a problem in that you CPU core temperature
is way too high. Read the entire article as it
has good photo, tips and one in particular about
4-pin vs 3-pin motherboard fan power connectors.
On page 4 of this review you will see that a more
normal temperature (under heavy load) is about 29
degrees C.
Zalman CNPS9500-series heatsink review
http://www.frostytech.com/articleview.cfm?articleID=2026
It's possible the heatsink was not properly mounted to
the CPU or proper pre-cleaning and then application of
thermal paste was not followed. This could lead to higher
then normal CPU readings.
That new fan you ordered could do the trick and lower
those temperature. 50C is about as high a I would want
to go and Prime95 does push your CPU, if you open Task
Manager prior to starting Prime95 you can see both cores
jump to 100% load.

Oh I do clean that out about 3 times a month. Just did it about
2 weeks ago. I just ordered another fan with higher speed.
Debbie
The fact that it ran for 3+ hours is good.
Your PC is stable and the CPU voltage and
memory setting are in the safe range.
What I don't like is the 55 to 58 degree temperatures,
the variation is OK, but even 55 degrees seems too high.
I need to do some research to see if this is normal for your
CPU and the Heatsink/fan that you had installed.
One thing you can do if you haven't done so already is to
open the case cover and check for dust buildup in the fins
the are part of the CPU Heatsink.

I just ran the Prime95 for 3 hours and 21 minutes and there was
no errors or problems. The temp got up to 58c the highest and
55c the lowest, it kept jumping for 55, 56, 57 58, it didn't
stay on one temp.
Debbie
Your CPU temp reached 70C, is that correct?
If it is you have a CPU cooling problem.

No I didn't run it yet. After I get done running errors
later I will run it. I did run a stress test in the Everest
and the temps got up to around 53c until the stupid virus
scan kicked in then it shot up to 70 so I shut the pc down.
Debbie
Core Voltage 0.85V - 1.3625V range.
Your fine.
Did you run Prime95 yet?

http://www.pagestart.com
The thing is it is considered overclocking by 3%. I have
left all voltages alone, right now the core voltage is
1.192 and sometimes goes to 1.184, so is that good? Core
speed is 3185.0, bus speed 335.3, rated FSB 1341.1, DRAM
freq 536.4
Debbie
Most BIOSs that allow you choose either an
'Auto' or manually when setting the CPU and Memory
voltages. Since you are not overclocking set it to 'Auto'
(Make a note of the current voltage settings if you have
changed them)
and then run Prime95.

I didn't put the CPU in myself, I had the techs do that, I
didn't want to mess with that. I just bought the part and
had them install it so I don't know what kind of paste
they used. I replaced the stock fan with a Zalman 9500A
92mm. My pc always ran in the 40c's even with a side fan
and I just recently added a third fan in the front. The
case is in a enclosed shelf in the desk. I always keep
the door open a bit for the air to get around in there.
What about the voltage, do I need to change it?
Debbie
Did you run Prime95 I mentioned in my earlier
post?
Your CPU Temp (CPU 45c) looks a little high,
are you using the stock Intel Heatsink and Fan?
If you are not using Intel's stock heatsink and
since assembled this system yourself what did
Heatsink and Thermal paste did you use.
Prime95 "Stress Test"
"FREE MERSENNE PRIME SEARCH SOFTWARE"
http://www.mersenne.org/freesoft/
Download and unzip. It's a standalone .exe file
when you first start this program you will see
a "Welcome to GIMPS" window. bottom right click
on the "Just Stress Testing" button. In the
"Run a Torture Test" window select the "Blend"
option. Leave the "Number of threads to run"
at 2. Don't forget to start SpeedFan before running
Prime95 so you can monitor your CPU temperature.
When your done running Prime95 use the menu to stop
the test, if you don't and just X out it will still be
running
in the background in which case you will need to open
Task Manager to Kill the Prime95 process.
I Personally turn my PCs off at night even though each
PC has it's own UPS power backup unit, why keep the
system running when your sleeping.

Oh my I would never clock it up that high. Now since I
did all this I don't have to adjust any voltages do I?
My temps right now are CPU 45c and MB 42c. I have a
fan on the side and one in the front. One in the back
and a new one on the CPU. Now I usually keep the pc on
all night, should I shut it down instead?
The processor is running at proper speed but it is
still calling it overclocked. I think I read on some
reviews that some people had to adjust it to get the
right speeds. So I'm good to go then?
Debbie
Also about half way down this page:
http://www.overclockersclub.com/reviews/intel_e8500/3.htm
You will see some screen shots of just how fast they
were able to overclock their test system.
I do not recommend overclocking as you may
void your warranty. So if you are happy with
the performance now that the processor is running
at the proper speed, leave it that way.
