e8200 temps too high?

[Akagi]

Im running an e8200 under the intel stock cooler (with the larger heatsink, the one supplied originally with the e8200) with arctic silver 5 (applied 3 days ago) and it is sitting at 40*C idle, and it soared up to 84*C on prime95 blend!

Stock clocks and volts as well

Isnt this too high? I thought the maximum safe temp was 72.4 for these chips?

Using HW Monitor to get temps.
I'm convinced that this is totally wrong though, if i touch my hand to the heatsink while HW Monitor is reading 84*C, it feels cold, and the air coming off of the cooler also feels cold.
I am pretty sure that the cooler is mounted properly because the TIM spread evenly when i fitted the heatsink, and there is definite contact between the heatsink and the CPU. The push pins are all in fully, and in the locked position also.

Could this be a problem with HWMonitor or the onboard temperature sensors?

Can you suggest another program i could use?

I am going to try coretemp in a second.

Coretemp gives the same readings.

Reseated the CPU cooler, readings appear the same. Thermal paste hasnt cured at all yet, still gloopy in consitency.

I replaced the push-pins on the CPU cooler before i fitted it as the old ones were broken.

The ones i used were off of a cooler supplied with my socket 1155 i5 2500k, but they appeared to be identical. The i5 stock cooler did not make contact with the CPU, hence why i had to fix the socket 775 one instead... I was under the impression that the intel stock coolers were supposed to be universal?

*update*

I re-seated the cooler again, and this time noticed that the push pins were not quite twisted far enough around (litterally a tiny bit more movement, hardly noticeable) was achieved when i put some effort into twisting them a little more (didnt have a screwdriver to hand)

Idle is now 39*C, load on prime so far (after 5 minutes) is 51*C
