Default CPU Heatsink

I bought this fan, Compared it to other fans. i read all the reviews, a bunch of people were saying how quiet it was. and how their CPU temps were idling at 40-45. while mine idles at 50-55. Is something wrong?

What thermal interface did you use? Thermal paste? Pads?

What kind? Arctic Silver 5? Arctic Ceramique? Or I should say: what brand?

How much did you apply? A little rice sized dot? A blob?

It may have to do with your ambient air temps, these people saying they idle at 40-45 they are in the reviews? you have no idea of their ambient air temps when they get these readings, for all you know it could be in winter.

What was the thermal compound? silicone based or silver based?

Yeah, ambient case temperatures also factor into the general performance of your heatsink.

That's the problem. That is a NO-NO.

You want to use a little dot about the size of a grain of rice and just spread it around. You use too much paste and it becomes an insulator, not a conductor.

Whilst the instructions in THIS LINK are AS5 specific they're a good guide to applying thermal compound
