Do I have a dodgy cpu?

Ok, this is a new attempt to get this answered.

I built myself a new i5 system a couple of weeks back and now I'm getting worried about my cpu temps at full load. I'm using an Alpenfoehn Brocken cooler and the cpu is at stock speed but with all cores at 100% it reaches a disturbing 84C!

I've made sure the heatsink is seated properly and I used the thermal paste that came with the cooler (possibly too much?) so what else could be giving me such high temps? My idle temps are 29-31C, and the heat dissipates within a few seconds after load dropping back down to the low 40s.

I am worried about this so any help would be greatly appreciated.
 
I think airflow is fine. I have an Antec 300 and the cpu fan blows thru the heatsink and out the rear case fan. Case temps are reading 30C +/- a degree or two. I suppose there might be some minor obstruction to the cpu fan with the cables from my optical drives but I don't know if it'd be enough to hugely impact performance... I'll see if I can get a picture up.
 
But this is meant to be a pretty good cooler. I really don't want to be replacing it after 2 weeks when it should be more than capable of doing the job.
 
Right, might be more of an issue here than I thought as both real temp and core temp are reporting idle temperatures of 50C while the Asus program at the same time is showing 35C.

Fan is working fine as far as I can tell, and it scales up its speed as temperature rises, and at 100% it's at 1430rpm.

How much impact can too much thermal paste have? Can't see it throwing temperatures up a good 30C
 
Ok, cool. I'm off tomorrow so I'll remove it, check the flatness and re-apply the paste.

Am I right in assuming that for intel chips the paste is best applied pea sized and in the centre allowing the heatsink to spread it? Also, what's the best way of removing the residual old paste?
 
Hey setter, is there a common name for that stuff? You know how us norn arn folk like renaming things. I'm just down the road in Ballymoney by the way.
 
I think everything is working normally now, other than Asus AI suite misreporting cpu temperatures.

I checked everything with the heatsink and it looked fine, gave everything a good clean and put fresh thermal paste on and now, using coretemp to monitor during the intel burn test the hottest any of the cores hit was 54C.

I suppose there might have been air pockets between the heatsink and cpu or something but you just can't tell by looking after you've taken it off.

By the way, is there any reason that the AI suite would be giving such way out temperatures? It tells me I idle at 21C now and coretemp tells me its ~30C?
 
I'm confused... Speedfan is telling me it's in the 20C area as well, but what the hell is the AUX reading in speedfan? That one is around 30C

This is just me trying to find what's accurate to see what I actually have to work with when it comes to overclocking it.
