Installing 8400?

I've just installed a new E8400 having built a few systems in the passt and noticed some strange things going on.

Firstly, the CPU sitting in the socket seems to sit on the pins, rather than there being holes for the pins to go into. Is this right?

Secondly, installing the heatsink was a bitch and I had to use some serious force to get the last pin in (specifically getting the black pin through the clear pin on the bottom). Worried I've broken it slightly even though it's snug and stable and there's uneven contact BECAUSE:

Thirdly the temperature seems very worryingly high. I hear these should idle at around 25-35 degrees, even on the stock cooler. Using Speedfan, I get readings of

System: 29
CPU: 37:
AUX: 27
Core 0: 49
Core 1: 60 (with a little flame symbol)

Coretemp gives me the same readings.

I haven't installed any drivers (including mobo or cpu) yet as I wanted to check if everything was OK first... which it doesn't look like it is!!

Could someone let me know if this sounds dodgy?

I'm probably just going to shut the whole thing down and get a new cooler in there.

edit: Didn't see any film or anything over the cpu surface or over the pre-applied compounds strips on the HSF and on removing the HSF to re-seat it, it looked like it had spread out OK.

Firstly - Yip socket 775 has the pins on the motherboard rather on the CPU.

Secondly - The push-pins are infamous for being a **** to fit. Going in a criss-cross motion usually helps.

Thirdly - You're correct to be worried. Are all 4 black pins definately through the board? But the motherboard may just need a BIOS update to correctly read the temps. Which motherboard is it?
 
P5Q Pro

I may try installing drivers and updating the BIOS now then.

If that doesn't work, I'll switch the PC off and get some AS5, some of that cleaning fluid and a Freezer 7 Pro.

Sensible plan?

Thanks for the quick advice!
 
The P5Q Pro *should* show the correct temps for an E8400 without needing a BIOS update. What CPU temp does it display in the BIOS?
 
mine in my lanbox idles around the 40 mark and hits 58oc with prime running 8 hours but i have a freezer 7 low profile on it as oposed to the stock
 
Intel HSF are fine indeed. On my old E2160 I got it to 3.0Ghz on temps that are good, no worries. For stock they should be good.
 
Probably a lot better on the lower end / 45nm tech.

On my Q6600 it idled at around 55c, didnt even want to try load temps
 
Recommend the Freezer 7 Pro then as an alternative?

Or would the Akasa equivalent (which looks almost identical, but is cheaper and various users here seem to rate it) be a better bet?

Cheers

edit:

Also, are the pins on these non-stock coolers any better than the intel ones? I don't relish the thought of breaking one of these after spending £15-20 on it.
 
Well, I've installed my Freezer 7 Pro (the pins went in much easier than the stock), but the temps were the same. Plucked up the guts to run Prime95 and... well, the temps don't go up much at all. Just a couple of degrees. Doesn't that seem odd?

The other strange thing though, which is more concerning is that the cooler is still not warm to the touch after 15 minutes of prime-95ing.

What on earth is going on? Are my sensors on the CPU just telling lies? I guess if this is the case, I ought to get a replacement as these (I undestand) control the fan speed, which as a result is constantly maxed out and quite loud.

What do you experts reckon?
 
Thanks Cob

I've run the test sensors a few times and have got a hell of a range of results. From 0 and 7, through 6 and 6 to 1 and 1, and 4 and 2.

It's a bit of a mess really. Since I'm not overclocking and it's not shutting down or even showing any increase after heavy stress testing, I'm going to assume that it's safe to use and that the temperatures are lying
 
They're lying on mine. I've got temps on the low 60's idle, high 60's load, & I've checked/resteated the cooler 3 times.
