    I've upgraded my Q6600 to a Q6850 and the computer is crashing (blue screen) about once a day. Could this be that I need to upgrade the fan?

    On SpeedFan 4.4.2 I'm getting the following reading

    Temp 1 70c
    Temp 2 44c

    CPU -64c
    Internal Temp 53c

    I'm not sure if these are the correct readings to give.

    Any ideas on this would be so appreciated :)

    Hey there,

    It could be that you need a better fan. However, Did you make sure that you used a good quality thermal paste when fitting the cooler back on? Are all the push pins connected tightly and locked correctly?

    Intel coolers are very hard to fit if you haven't done it before and I have had problems with them before.

    Thanks for the reply :)

    I got the paste from PC World, so I presume its good quality. Maybe I didn't put enought, on? How thick should the layer be?

    Usually you need to just put a small blob (about the size of one of those plastic bb bullets) right in the centre of the CPU, Then as you push the heat-sink down onto the CPU and lock the legs that spreads the thermal paste enough to make it have full contact. Remember make sure that all the old stuff has been removed as well, I just use a paper towel or kitchen towel sort of thing and just rub the thermal paste off the CPU and heat-sink.

    If you watch this video it shows you how thermal paste will spread. If you base your application on whether you have metal or ceramic compound then you can make a decision on the best way to apply it. http://www.youtube.com/watch?v=EyXLu1Ms-q4

    Good vid, cheers. I think I've put too much on, would that cause blue screen?

    It's ahrd to describe exactly the amount of compound to use, but I use an amount about the size of 2-bb's right in the center of the heatspreader whether I'm using AS5 of IC7.

    When Shop Intel was still open they had pre-filled syringes of Dow-Corning TC-1996 compound and you emptied the whole syringe in the middle of the heatspreader which made it very easy since you didn't have to guess at the proper amount.

    Here are some good directions for applying IC7 and as I stated I use the same amount whether I use IC7 or AS5.

    I don't know abut Blue screens, but too much thermal paste can create a thermal blanket that holds too much heat.

    As for cleaning the old thermal compound off, I use Denatured Alcohol and a piece of soft cotton t-shirt material.
