    make absolutely sure the water block is making total and complete contact with the IHS. Are you using a thermal compound? If you're not, you should be. Get some Arctic Silver 3 or 5.

    Are you sure you have coolant circulating??

    edit: just saw your edit. You don't have a thermal pad on there do you? Just the thermal compound, right??

    Wet sand the CPU side of the heatsink/water block with 220 grit paper, then 400, then 600 grit by putting the paper on a smooth glass surface so it sands it perfectly smooth. Wipe it down with alcohol and apply Arctic Silver 5 to the heatsink and clamp it in place.

    I did that with my Volcano 9 and dropped 3-4 degrees using just Arctic Alumina (computer temperatures should always be measured in C not F).

    I use Ceramique and one of these Zalman coolers. It is the 120mm model; dead silent and great heat dissipation!


    They come pre-lapped with a very smooth conductive surface, and ship with some thermal paste (that I threw away)..I always use AS Ceramique as it has worked the best for me.

    Best of all, the cool air that the fan sucks down into the heatsink then fans out over the entire motherboard, cooling every last exposed component!!

    So I now have active RAM cooling and a very chilly Northbridge chip as a freebie to go with my utterly silent CPU cooler...can't complain too much about that!

    That CPU temp is pretty high, is that idle temp or the temp while gaming?

    Whats the room temp ? my PC will get close to that if i play in when my room is 90F, i typically go fine something else to do when its that hot upstairs.

    I had about 6 browsers open. The room that it is located in is about 78 degrees. I have the back of the PC about 3 inches from the wall. Should I move it out a bit more for the fans in the rear of the PC?

    that may help a bit but i think you need another fan in the case or a better CPU fan and heat sink like the Zalman pic in this thread.

    I am not an expert i am just learning that my PCs are running a little hot and i have ordered the Zalman fans for them and new cases. The case i will be using ( Thermaltake Tsunami) has two 120mm fans along with the 120mm fan in the OCZ PSU i am using. I will be adding the Zalman CPU fan also once they get here on Tuesday. I also got rid of all the crappy ribbon cables and got round cables for all devices and neatly secured the wires to allow better air circulation.

    I supose i need a thermal paste now that i see most people are using it as well.

    Have you blown out the PC to get rid of all the dust from the MB and PSU fan and CPU fan? Sounds like you need more cooling as i did. Add a fan or two they are cheap if your on a budget and clean up your wiring inside the case.

    Yes, I just opened the case about 2 weeks ago and used about 2 cans of compressed air cleaning it out. I have had this machine about 2 1/2 years now and I haven't had any trouble with crashes or any strange happenings.

    This Vaio case is so small, I don't think one of these big fans will fit in there.

    Thanks for the ideas!
