CPU too hot or is it???

Hi just recently i got a 'Freezer 7' cpu cooler installed.
I have checked the specs of this cooler and thought it would eradicate the noise that was made by my previous pentium cpu fan.

My processor is a 3.4ghz 775 socket -- and what i wanted to find out is that -- the temperature that i am getting when my cpu is on 100% goes near 73 celcius.
What i dont understand is that with the pentium cooler, my cpu temp in 100% was around 55-60 c.

Is there anything wrong. The technicians in my local pc shop (who installed it for me) said that those temperatures are normal for a 775 because they produce a lot of heat.

Please help me on this!!
cheers

This test got much lower temperatures click here.
I wonder if the case cooling is adequate. It doesn't matter how good the heatsink is if the air it is drawing in is hot.

I've had a look at the link Gongoozler gave and from what the review says it should be cooler and quieter therefore I think as Gongoozler has suggested that the case cooling may not be sufficient.

It sounds a bit too hot to me, I would not be satisfied and would return it to the shop.

Tell them to put it back as it was and get your money back then click here#_ and scroll down to 'Fitting a Pentium 4 and Heatsink' and see if you fancy trying it for yourself.

Common mistakes are, 1) not removing the plastic protective cover from the heatsink face which causes damage to CPU and prevents correct contact between CPU and Heatsink so will not cool properly.

2) Not using thermal paste which prevents correct contact and prevents proper cooling.

3) Using thermal paste when a themal pad is fitted to heatsink also prevents proper cooling

4) Incorrect alignment of heatsink (more common with AMD chips)

5) Fan speed is too low either due to a setting or having a resistor inline or not wired correctly.

It might even be that the fan is not working, take the cover off and check.

or even installing fan the wrong way round..

Having looked at the Freezer 7 it is not likely to happen as the fan and h/s are built as one.

You should switch off at 80 degrees C - so you are obviously getting worryingly close!

..then it must be one of your suggestions, because it shouldn't be running as hot as that

The advice has got to be switch it off till we find the cause 'cos otherwise it will fry

I tried opening the case and saw a difference.
the temp drops to 55-58 and on full 100% it stays just under 70.
I'm thinkin should i change the case -- then again the pentium fan kept it much cooler then this one.

I just dont know wot to do.

I still have got my zalman cooler -- which is still sealed new -- but it doesnt fit into my case cos it so big -- maybe the zalman might be better than the freezer.

Take it back to the shop and tell them you are not satisfied, tell them what the problem is and if they can't or won't fix it then demand your money back and get them to put it back as it was.

It is definitely not right, the Freezer 7 should be capable of lower temps than the stock Pentium cooler.

My old P4 runs at around 39 but jumps up to 75 at 100%. At the risk of being called a neanderthal, I admit to keeping it under control by sliding the side off the case and popping in a couple of freezer packs and if really concerned, my daughters hair dryer on the cool setting takes it down a few notches. yes I know, bit dodgy!
