I upgraded my computer recently to a new motherboard/cpu/etc.. and I'm
having a lot of overheating issues with it when I do intense 3D renders.

At present I have the following:

GIGABYTE GA-MA78G-DS3H AM2+/AM2 AMD 780G HDMI ATX AMD Motherboard
AMD Athlon 64 X2 4800+ Brisbane 2.5GHz 2 x 512KB L2 Cache Socket AM2 65W
Dual-Core Processor

At first I was using the stock fan that came in the retail box for the
processor, but after reading numerous reviews on NewEgg, I upgraded to a

ARCTIC COOLING Freezer 64 Pro 92mm CPU Cooler

However, it's only marginally better. Not the great performance others
have claimed.

I am not overclocking the system at all and I did use Arctic Silver
compound when I installed the heat sink.

I am planning on upgraded to a QuadCore CPU in the next month, but I'm
concerned I may have issue with that as well.

Any tips? Any sites I should visit?

Thanks!

It should have been fine with the stock cpu fan and better with the Artic
cooler as long as it's rated for the 4800, and you applied a thin layer
of Artic Silver.

Check your internal cooling, dust and room temps. Some applications
will overheat a cpu and lowering the room temp helps keep it cool.

Thanks much. The location of my computer does have some wild
fluctuations in temperature.

Right now the room temp is 72f (system temp is 109f). The processor is
running at 102f (39c), however, if I start a render in Cinema 4D using
both cores it quickly jumps to 127f (53c) and then slowly rises to 141f
(61c) and if the render is long enough it'll go up enough to shut the
system down. The system temp goes up to 111f (44c) max.

I've got two case fans, one in the back blowing in (towards the CPU fan
and in the same direction as the CPU fan) and one in the front blowing
out. So the airflow pulls from the back, across the system and out the
front.

Your air flow is reversed. Cool air should be pulled in from the front,
the CPU fan should be oriented so air is pushed out the back (if you
have the type heatsink/fan where you have a choice), with the back case
fan exhausting the hot case air.

Just reverse the air flow and you should see an improvement.

No idea of what too hot is to you -- to me, 125F. Some people
disagree, but I've never liked an AMD much above 115F. Sparkle server
PS that weighs same as a brick. Not sure offhand if it vents over the
CPU, but in the summer if I don't keep the front grill clean, I've
encountered problems w/an A64/3G. Put some Panaflow or 120mm 100cfm
minute thing Newegg was giving away on the back plane mount. Don't be
fooled just because it looks like a case, it's really a jet airplane
that vacuums floors in a pinch.

Crap. Okay, well any recommendations on a different processor fan?

I can't turn mine around, or the fan will block all of the memory slots.

Remove the fan from the heatsink, turn it around, remount. The airflow
will now be reversed. Not ideal, but better than what you have. Most
heatsink/fans I've seen have the fan mounted on the inside of the
heatsink and have plenty of clearance for the memory modules.

What heatsink/fan are you using that the fan won't fit on the inside?

Ummmm.... he's saying turn the case fans around. If your CPU cooler fan is
situated so that it is fighting the rear case fan (if the rear case fan is
blowing air out of the case), you'd be better off physically REMOVING the
rear case fan, and using the front case fan pulling air INTO the case.

You don't have to change your CPU cooler. The original cooler is fine, the
one you bought to replace it is fine also...and it's probably installed
correctly. Your problem with cooling is your case.

You need at least one fan pulling cool air INto the case, situated down low
in the front of the case. If this is your only fan pulling cool air in, it
should be a high volume airflow (high CFM) fan. It would help if you also
had a fan in the rear of the case, mounted high, pushing air out of the case
(low CFM). But the rear fan is optional, as you also have a power supply
fan that pulls some warm air out in that area.

The problem with your original setup is that you had a small circle of hot
air that went out of the power supply (hot), back into the case (hot), then
through the CPU (hot), and back into the power supply (hot). You never
introduced any cool air into the loop. -Dave
