P4 3.0E Ghz - Heat Problem Please Help!

Hi Guys,
The problem is that I have a P4 3E GHz processor and I think its running too hot. I have 3 fans + CPU fan in total, these are:

2 Zalman 80mm ZM-F1 fans - one at front and one on the case side
1 Antec 120mm SmartCool on the back as an exhaust
1 Zalman CNPS7000B CPU fan

I thought all this was gonna keep my CPU pretty cool, as I have a full sized case with 1 dvd and 1 hdd so air flow is good, but running two copies of Prime95 in torture mode (i.e. cpu maxed out) and I have temperatures about 75 degrees C.
My case is at 41 degrees C, and PWM at 66 degrees C. Also my CPU Core Voltage is 1.35. i haven't overclocked or anything and both 80mm are drawing air in the the 120mm pushing air out the case. Also i am using Arctic Silver 5 thermal paste for the cpu and heatsink.
I have a Abit AI7 motherboard.
Finally I dont know if this makes any difference but I also have a Zalman ZM80D-HP Passive Graphics Card Cooler.
Please help me find a way to ensure the maximum temperature ever is 69 degrees C (intels max allowed).
Thankyou In Advance!

Did you follow the instructions for the AS5 exactly? If there's too much of that stuff between the processor and the heat sink it can actually reduce heat transfer.

Yup pretty sure I did - half a BB on the cpu, place on heatsink twist two or three degrees left then right and screw in! Got any ideas?

Is the CPU fan blowing into the heatsink or out?

If you have good ins and outs on the case, tehre shouldn't be that much of a problem with cooling it, provided you don't have it stuffed with accessories and such. You could try routing the cables a little differently and see if that makes a difference.

What are you using to measure the temps? Many built-in motherboard monitors are way off, for instance, the PII that I powered up last night from a cold state told me the CPU was running at 75C, and the device had been on for at most three mintes for the first time in a couple months. I know my garage wasn't that hot.

So it may be that your monitor is not calibrated, see if you can verify the temps with something else.

Hi and thanks for taking the time to reply .
Ok, as to my cpu fan i guess its blowing away, i havent changed the direction of the zalman fan and i dont think i can.
I'm using MBM to measure my temperatures, as its an abit motherboard i've heard they can report a few degrees higher.
Also I've bought rounded cables and i took the time to move and tie all the cables to the side when i first built it so air flow should be pretty good. I think it would be a good idea to verify the temperatures but how would you use something to measure the temperature of the cpu without removing the heatsink? Thanks for the help.

A not-quite-accurate but pretty close method it to place a thermometer against the heat sink close to the CPU and see what temperature the heat sink is sitting at. The CPU will be a tad hotter than that, but it give you at least a ball-park estimate of how far off your motherboard sensors are.

Well firstly, its a prescott so it's allowed to go up to 95C but no more than 70C for long periods of time.

Secondly, you done all of the standard stuff (apply as5 properly, check fans are spinning, etc)?

Thirldly, its a prescott so it has alot of room for overclocking, voltage-wise, which means the inverse is quite true, you can lower the voltage to reduce temperatures. Just lower it 0.025V at a time through your bios, run a few tests (p95, spi, etc) to test if its stable. That'll bring down temps really well depending on the quality of your chip.

Hi, already thought about that and was wondering if you could help with it. My motherboard is an abit ai7 and in the bios settings i'm pretty sure is at minimum voltage, i can turn it up but not down, its at about 1.37 now i think.
