Arctic Silver Ceramique

[BackBonE]

Well I had Epox 8rda+ with its standard NB passive cooler, and always got a NB heat similar to my CPU heat (around 32°). I decided to buy an active cooler for the NB and got Vantec CCB-A1C and installed old NB cooler on the SB. But instead of Arctic Silver 3 this time I used Ceramique. Thoug it says it needs 12h to get neat results, I got suspicious since now my CPU and NB heats are the same 34°. Anyone out there tried out this termal paste?

How do you measure NB temp anyway ?
Haven't tried Ceramique yet, but I'd love to, unfortunately it's impossible to find where I live.

Don't tell me what winbond3 measures is something else!?!

I have no idea what that sensor measures, but I kinda doubt it can measure the NB temp.

Now I doubt it too! After 12h my WB2 and WB3 temp are still close (2 to 5° gap). I firstly thought that ceramique was lame, but it ain't I used it on CPU and went down ~2°. Then I slowed down the NB Fan and voila no change on the winbond3. I think it measures case temp, but how I wonder?

Perhaps there's a thermistor "bead" that sits above the mainboard's surface?

BackBonE,

Unfortunately there is no easy way to measure the temperature of the Northbridge. The Winbond temps are measured on the Winbond chip, not the Northbridge. Have a look at your board and you should be able to find the Winbond chip.

The most likely reason you are seeing an increase in temps from the Winbond chip is due to the change in heat and airflow from the additional Northbridge cooling.

Well my Mobo uses a W83627HF. Regarding to winbond's web site: An 8-bit analog-to-digital converter (ADC) was built inside W83627HF. The W83627HF can simultaneously monitor 9 analog voltage inputs, 3 fan tachometer inputs, 3 remote temperature, one case-open detection signal. The remote temperature sensing can be performed by thermistors, or 2N3904 NPN-type transistors, or directly from IntelTM Deschutes CPU thermal diode output.

I aslo found out the pins:
VREF: Reference Voltage for temp. measuration. - this is the bogus WB1
VTIN2: Temp. Sensor2 input - CPU
VTIN1: Temp. Sensor1 input -System

So there are two thermistors. One is under CPU I believe? I don't know about the other mysterious one, since I have no idea what tthese thermistors look like.

Isnt the system temp in the BIOS the NB temp?

You could measure NB temp with those little temp measuring thingys (that was helpful lol) forget what they are claled just put thermal paste on bottom and top

I belive you'll find cloasters is the closest to the mark.
During my time as a hardware techi, i've played with quite a few motherboards and cans of air-duster (turn the can upside down and it spits out fluid at about -70c).
using the air-duster as a freezing tool i located the system temp monitor on a few motherboard i used at the time, motherbaord temps of -40c? hell yeah >

It usually located just below the southbridge towards the bottom right corner or the motherboard, positions can change from brand to brand but its usually there. its just a very small surface mounted thermistor.
it's practiacally impossible to find without freezing the motherboard with this spray, just watch the temps in the bois and wait for it to drop down real fast. i've never damaged a motherboard doing this either.

It also makes for the cheapest extream cpu cooling you can get. £1 a can or something and you can get heatsink temps of about -40c, then just go for the insane over clock before the can runs out >

Well thanks for all your posts. I use a Coolermaster hhc-01 on the CPU, A Vantec CCB-A1C on the NB, Epox's standart passive NB cooler is on the SB, a 12cm Delta AFB1212LE (84.76 max CFM) on the rear panel and two 8cm Deltas AFB0812L (27.9 max CFM) on front panel below hdd. I control all my fans with Zalman mfc-01.

Now as I also wanted to silence my system I've got 2 options:

1. System:32°, CPU:40°, GPU:67°
CPU: @2500rpm
NB: @5000rpm
8cm fronts: in @2500rpm
12rear: out@1200rpm

1. System:35°, CPU:37°, GPU:71°
CPU: @2500rpm
NB: ~2500rpm (I can not measure)
8cm fronts: in @2000rpm
12rear: in@1200rpm

I used a FX5600 with 44.03dets for these tests, since it has temp. monitoring, but I'll normaly will continue with my Ti4200 since its faster?!?

So which setup should I go with?
