CPU Overheating?

bloodline76 · 22 Jan 2008 at 19:10

I have just changed over tower and think my cpu cooler might not be on correctly.

Before it had four fans and was running at 30-40 idle and 60-65 on full

But now i have changed over to a new tower I have less fans but they are bigger. Idle is down to about 25-30 which is great but on full it begins to throttle.

I think the case is cooler than before as even the graphics card is down about 5-10 degrees.

But why would it be cooler on idle than it was before but over heating on full?

Any advice?

Thanks

One thing I do remember is that I out a lot of thermal paste on, could i have put too much on?

usually, isnt the advise to put on as little as possible?

if you have any spare, reseating the heatsink will not hurt and it will eliminate that possible reason for the throttling

download coretemp and post you load temps...

first thing I would try if they are high is to reseat the heatsink

Coretemp readings

Tj Max 85degrees
Core#0 35degrees
Core#01 31degrees

When you say reseat the heatsink you mean the cpu fan?

by heatsink i mean the cpu cooler

So is a thin spread of paste better? I think I over did it and put it on both the cpu and heatsink bit.

generally, most people will tell you that with thermalpaste, you should only apply as little as possible, this however does not take into account concaved or convexed IHS and/or coolers, where contact can be bad.

So do I just apply a reasonable amount on the cpu only, I think I went over kill.
