Core 2 Duo core temp problem

A friend of mine just upgraded to a Asus P5N-E SLi motherboard and E6300. The problem is various monitoring programs seem to be giving very different values. When the system was first setup I tried CoreTemp, this showed both cores at around 59c idle. Which I thought was quite high given that there's no overclock going on here. So I tried PC Probe II, which gave a value of 39c. So I then tried Speedfan, this gave me quite a lot of temps (a lot more then usual). It had the usual HDD temps as well as core 0 and core 1 (listed as around 59c BTW). But it also listed tempt 1 twice and tempt 2 twice, all four with different values. I went into the BIOS and it was saying 40c. All very confusing.. Oh and just to round things off Speedfan also reported my friends heatsink fan as 1350000RPM, which if correct would mean that his case would likely be flying somewhere over mexico by now :lol:

So has anyone ever heard of this kind of problem with the P5N-E? If so what's the definitive way to know 100% what the core temp is actually at (I would have thought the BIOS, but is it showing the core of the socket?).
 
speedfan and TAT both get the core temps directly from the CPU, if there both saying 59c then that would be about right which is very hot
 
I'd never heard of TAT, I'll download that and try it out next time I'm over there, thanks.

Yeah I thought Speedfan and CoreTemp where supposed to be the most accurate (though speedfan is obviously misreporting fan speed and some power values on his system). But at the same time when its giving me readings of 59 the heatsink is cool. Its installed correctly, so how can it be cool with a CPU burning away at 59c underneath?

Also why does Speedfan give him like 7 different temp readings (plus HDD readings) when it normally only gives about 5 plus HDD.

I think what I'm going to do is post pics of some of the programs so you guys can have a look. Thanks for the help

Could be that the heatsink has become unseated. I thought this was a weird idea when someone mentioned it to me about mine, my CPU was running a lot hotter than normal after switching cases. I changed the heatsink and voila, normal temperatures resumed.

Dont bother with TAT it doesnt work on the P5N-E. The temps obtained from Coretemp are reliable.
 
After looking at some reviews online I'm beginning to think this problem is down to the heatsink Intel supply with the E6300. People seem to be quite unhappy with it and often report 50+c idle temps (this one is 52/54 idle and 60/63 under heavy load). Now that I've had a look at the thing it really doesn't look like a particularly good heatsink either. The base is round and doesn't even cover the CPU fully and the fan, which isn't big the start with, only runs at just under 2000RPM. So it looks like I'll be advising my friend to get a new heatsink as soon as possible. Until then is there any way of increasing the fan speed on the stock heatsink?

Also what voltage is best to run the E6300 at if its not going to be overclocked at all. There seems to be some confusing on what the stock voltage is supposed to be (1.35 on the both, 1.325 reported elsewhere and I see people overclocked to 3Ghz with 1.29!..).

I've been reading in the overclocking section about the E6300. I came accross a thread about the problem with these chips sometimes having concave heatspreaders. When I removed the heatsink to reseat it earlier I noticed a very slight circular mark around the chips heat spreader (matching the circular base of the heatsink). Is this an indication that this chip is concave? So that perhaps the sides of the heatsink base are contacting with the chip but not the center?
 
Problem solved. I took the heatsink off again to try to see if there was any problem with the chip being concave. As far as I could see there wasn't any problem. So I decided to simply try putting a thicker layer of paste directly on the heatsink (instead of on the CPU, since the heatsink base doesn't cover the entire CPU spreader anyway). Started up and temps where 38/39 idle. I'm converting a movie at the moment using 95% of the CPU and its sitting at 45/47!

Thanks to everyone for posting.
