Antec P180 and Asus P5B

fredz · Post by **fredz** » Mon Apr 23, 2007 3:58 am

I have got a system with these specs:

- Antec P180
- Asus P5B
- Intel E6700 C2D
- Asus EN8800GTS

I replace the stock case fans in the P180 with Noctua NF-S12 fans. The one down at the hard drives is running at 1200rpm, the two other ones (top and back) are running at 600rpm (ULNA).
I also replaced the stock Intel fan with a Zalman 9500 LED fan, which I have now running at about 2000rpm. I am getting temperatures (idle) of about 45Â°C CPU and 52Â°C MB.

Are these temperatures high? For me, the most important is the quietness of the system. I will not overclock my processor. I can run the fans at higher speeds, but find the system a LOT louder. What do you think?

Those are decent temperatures; the MB is a tad hot (I have a P5B Dlx and the MB temp never gets above 46C, even after 24hr+ of Intel TAT), but the CPU temp is quite ok (I get loads of up to 60C+ (core) and ~54C (according cu ASUS Probe) with Intel TAT), so 45C is quite ok, if it's a load temperature

Hello,

A 2000RPM (120mm?) on the CPU can't be very quiet. Is the 45C CPU temp under load, or idle?

Those are all idle temps!
The CPU cooler is the Zalman 9500, which I have now running at 2000 rpm (halfway between max and min).

According to the asus FAQ the motherboard temperature is in the normal range between 40-60 degrees Celsius.

If it helps to compare with a similar setup:

-P180B
-P5B deluxe non-wifi
-8800GTS 640
-e6600 (stock settings)
-Tuniq Tower 120
-4 Scythe S-Flex E at 7V (fan controller)

I get 28 idle, 38 in heavy gaming, 45 under TAT

YES STEFX!!!! TUNIQ TOWER 120. I finally got mine!

Back to the subject, I agree completly with what everyone is saying, run TAT and see. You may want to upgrade the northbridge to a thermalright or noctua northbridge cooler--if you can fit it in.

How does one upgrade the north bridge on the P5B-D when it has the heat pipe and everything?

I have the P5B-D-wifi in a P180B and OCing my E6400 to 3.4, the NB gets a tad warm. And what aftermarket cooler would you stick on the NB? Would the SB get anything special?

Remove the top plate covering the NB heatsink's fins, that'll help. Connect a low-profile fan to the area above the VRM's will help as well, since they're joined by heat pipes. IIRC there's one guide out there where they do that, plus the remove the whole setup and clean off/apply new thermal grease to it.

SB shouldn't need anything special.
