    I had trouble using timclean on the thickest TIM on the heatsink itself as it was very waxy, almost solid and crumbly. You may have different paste on your board though.

    If the MB gets extremely hot then uprating the thermal paste won't hurt but it probably won't help much. the time to be worried is if the heat sink is stone cold but thetemp readings are high. This is the situation where someone may need to re-do their TIM.

    It won't hurt to change it though. Let us know how you get on.

    The problem is, there is no sensor for NB temprature, so i cannot tell how well will it cool after i do it

    Well I bet you will be able to touch it longer, that will give you some indication. But ya to be exact you would need a sensor into the heatsink or directly beside the chip

    Thermaltake Extreme Spirit II works great for a NB Cooler and it is a decent price ($18-20), but you would need to buy something for your Mosfets if you used one of those

    If i need more cooling, i'll just put a 60mm or some similar sized fan on it, that should do more than enough.

    BTW, what is the MB Sensor for? In everest, under the sensor/temp section it says motherboard temprature 34deg C idling atm.

    Ya a 40-60mm fan will help alot, you'd be surprised!

    MB Sensor is the PCB Near the NB and is Very close to what the actual NB Temps are. Here is some testing Kick did with P45 and this setting and a sensor in the NB >>>>

    I have an Antec 1200 case with a side fan on as an intake so i decided to do some testing - the NB sensor in everest under load after 15 min of Large FTT was reporting 36-37 deg C. I took the panel of for just over a minute, and that went to 38-39 deg C. I put it back on and it dropped to 37. So if that MB sensor is correct, under load the NB temp is around 37 deg. Thats not that high.

    That was on 460 x 8.5 = 3910 Mhz, Ram on 460 x 2.4 = 1104 (5-5-5-15, static tread value on 7). FSB overvoltage on +0.1, NB on +0.125, CPU showing ~1.328V in CPU-Z

    Ok, i've done that, easiest thing i have ever done! I unscrewed it, pushed those pins and pulled them out carefully and it just came off - The chip itself on the board has a heat spreader which is rather surprising, and there was a thermal pad, not a thermal paste which i peeled off from the sink. Then i had some old thermal paste, tested it out if it makes contact, wiped it off with 70% Alchocol, put some MX2 on there, spread it even with a credit card and placed everything back on. I tested with Lagre FFT in slightly hotter circumstances (room temp) and the MB temp sensor is reading probably one or two lower than before, and the heatsink itself on touch is a bit cooler now, but the pipes are about the same - thats expected.

    Now let's crank it up to +0.2V, and go 4Ghz :D



    PS. Forgot to take pics, would have been nice

    The NB had a heatspreader??? I have never seen this on any boards

    SB Yes, but not the NB

    NB had a heatspreader like a CPU, definately, it had a code on it sayng Swhatever, Intel Confidential 07 i think it was





    Something like that
