Do I need to look into cooling.

Hi,

I have seen a rise in CPU temperatures since doing an upgrade and am considering getting a dedicated CPU watercooler like the Antec or Corsair. My system currently runs on air (not bothered by noise) and has been fine I am just not sure what could increase the temperature so much?

I don't have much to spend on a new cooler and I don't intend on OC'ing although I might be tempted a little. Was looking at getting the Antec Kuler 620.

I know the CPU should not be allowed to go over 60 C so for me 51 C under load is a little too close for comfort.


Upgrade non OC Specs:

Antec P180 Case
OcUK Value GeForce GTX 470 1280MB GDDR5 PCI-E
AMD Phenom II X6 1055T
Gigabyte GA-880GM-UD2H AMD 880G mATX Motherboard
Crucial Ballistix Sport 16GB (4x4GB) DDR3 PC3-12800C10 1600MHz
x2 IDE Drives 320GB
x2 SATA 6GB Drives 500GB in RAID 0
DVD Burner
OcUK Crusade 850W Quad Rail High Efficiency '80 Plus' PSU (power to CPU from 2x4 pin plug)

CPU TEMPS:
IDLE - 41 C
LOAD - 50/51 C



Original non OC Specs:

Antec P180 Case
OcUK Value GeForce GTX 470 1280MB GDDR5 PCI-E
AMD Phenom II X6 1055T
Gigabyte GA-880GM-UD2H AMD 880G mATX Motherboard
Patriot Viper 4GB (2x2GB) DDR3 PC3-12800C7 1600MHz
x2 IDE Drives 320GB
Antec Noisetaker 600W PSU (power to CPU was by 4 pin plug only)

CPU TEMPS:
IDLE - 28 C
LOAD - 38/40 C

did you assemble this yourself?
if so, have you tried remounting your cpu cooler? the paste may have not spread properly.
also is the cpu overclocked at all?
and does it have the stock cooler attached?

also from what i have heard, the 620's seem to be decent, but a silver arrow is better in performance and quieter (ram allowing)

IF you run prime 95 for about an hour and take the max temp and see what that is , if you want it lowered then you could try adding a few more fans on your case or get more powerful fans to get more air moving :)
 
the ony change I have made is as shown... when I upgraded the ram, PSU and added 3 drives I did not touch the cooler which is an Artic Freezer so the temp variance shown above is from what I added to what was not there before.

I already have x5 120mm fans in the case, the x4 HDs are in the bottom compartment so no heat is getting into the mobo area.

The fins on the cooler are noticeable hotter than before.

I have not OC'd it as stated.
 
With the original power supply it just had a 4 pin connector for the cpu but I had a 8 pin connector on the motherboard, the new power supply has a 8 pin (2x4) cable connector so I plugged that in but it states in the manual its for server/workstation.

Could 8 pin over 4 pin being increasing the temperature?

What are the benefits of 8 pin input over 4 pin input?



I am using my computer for 3D work so require periods of long rendering times.
 
What are you using to measure the temps?

There is a big difference in the Tcasemax temp quoted and the actual temp in the CPU core. TJmax (internal) is usually quoted at 80-90C and is the internal temperature whereas the Tcasemax is the temperature at the interface between the CPU and the heatsink which is not directly measurable and since this is taken after the heat spreader this is always lower.

51C under load for a hex core CPU is a good result. Relax and enjoy your system, it's fine.

If the heat sink feels noticeably warmer then either you've increased the heat output of the CPU or affected the cooling.

I have the P180, PSU at the bottom so should have no effect on case temp.

Standard fans are three speed, have you knocked the speed switch on any of them.

Sounds like the CPU cooler is unplugged to be honest, can you visually check this is spinning, the Top and Back fans may be providing some CPU cooling.
These are often plugged in right near the memory.

Can you check the fan direction at the top and top back. Make sure they are exhausting.

Front fans should be blowing in.

Have you moved the PC since the original readings?

Is it near a radiator which is now running, that can have a big effect.

update: whilst trying to figure this out I looked at the cpu cooler to see if there were any problems... I guess I haven't checked my temps in a long time I as its covered in $%£& and dust I was going by temps I had when I first installed. doh! :D
