How can I get the temp down???

I use a P4 3.0G with the Zalman CNPS 7000 and my cpu temp at idle is around 40C and gets around 55 during load.

I bought the Zalman model becuase I saw it rated the best cpu cooler in lots of sites and magazines but the temperatures I'm getting aren't as good as its reputation.

Is this fan supposed to work this way or should I be getting better temperatures?

Is there a better hear sink for my P4?
 
1. The Zalman there is nice but certainly not the best.
2. Too much thermal paste? Not enough?
3. What processor core do you have? If its a Prescott then you're actually doing pretty decen
 
it actually is a Prescott...

Does that mean that I can't avoid the temperatures I'm getting right now??

what CPU cooler would you recommend with my specs?
 
The Pentium 4 3.0 [Prescott] would be a heatbucket so really yer doing pretty good (a bit higher than expect but not by much). You can have a second look at the thermal paste though. As for a reccomendation ... Tt Polo735 is my fav (cuz its out-of-the-box-brute-force) or a Thermalright XP90 (or XP90c) with a high CFM fan ... dunno if it fits S478 but i imagine it should
 
Air flow...

How about the air flow.
I am a believer that a good air flow helps.
You should have a front air intake with or without a fan,
and a rear fan for taking hot air out.
A front fan helps, but don´t worry, the rear fan
creates the air flow if you have a front air intake.
Intel also recommends a tunnel in front of the processor
(on the side of the case) to take fresh air from the outside of the case directly to the processor...
Good Luck...
 
Thanks a lot guys!

I'll take a look at some other coolers or maybe even get an AMD cpu/motherboard...so much for intel..
 
I have a prescott 3.0Ghz with ht, and my cpu runs at about 45C idle, and about 60C load. I think yours istn that bad. (Although i have no thermal paste and a stock heatsink/fan)
 
So you mean that the cpu I use dissapates a lot of heat...

Does this mean that the Prescott P4 can withstand heat compared to other processers that idle at around 30C?

Do all P4's produce lots of heat or its it only the Prescott P4's?

I heard that Pentium's Celeron produces low heat but the clock frequency for the Celeron's aren't as impressive as P4's...

No, it doesn't dissipate it, it creates it:P

AFAIK, all CPUs can withstand temps up to around 80*C

It is only the socket 478 prescotts that are bad, the socket T and the Northwoods are fine

They produce less heat because they don't do anything worth noting.....:D

Dont discount them quite yet ... their 5xx and later processors are significantly cooler

Yes.

Although ive alluded to and assume it in my above posts, I think its worth mentioning that "Prescott" processors come in two flavours for many clock speeds. In your specific case there is the Pentium 4 3.0Ghz (running a Prescott core) and there's also the Pentium 4 530 (also running the Prescott core). The difference is that the Pentium4 3.0Ghz is a Socket478 part and the Pentium4 530 is a Socket775 part. The S775 chip runs cooler.

AFAIK, all CPUs can withstand temps up to around 80*C

Consider a Sempron 2600, SDA2600AIO2BA max temp 69ºC
 
What do you think that the HSF does?
Click to expand...
The HSF is a less theramally resistive path for the heat. The heat is generated either way, just with a better conducting HSF the temperature at the processor is lower.

Sigh some kids never learn. If yer gonna argue thermo with Yeti, please do yer research ;) And you should (or should i say, 'will') stop this tactical ambiguity stuff ;)
 
i can understand what hes saying, hes saying that the CPU creates the heat, and the heatsing and fan dissapate the heat. And i can see why he would say that, because the CPU creates heat, and dissipates it.

Contradictions and incompleteness aside, everything that generates heat will dissipate it at some level. Of course in the case of a modern CPU, the net and effective result is that the processor is a producer of heat rather than a reliever.

Of course some heat leaks out and doesn't get to the heatsink, but it is very little like you said. Now how was this so hard?:P

No it wasnt. So next time make sure you know what yer talking about. Trying my patience isnt gonna work so well the third time around.
 
Bugger me i'm confused. And i dont want to get involved in an agrument or take sides but..
i thought
cpu =generates heat soley - (ingnoring the small net dissipating factor of all materials)

hsf (contact plate) =absorbs heat from cpu, due to low thermal resistance and low heat latency. Maybe you can call this dissipating but *i think* dissipating implies an element of scattering whereas the hsf is more a directed shifting of heat.

hsf (fan) =dissipates the heat into the air, here i use dissipate since the heat is scattered out into the air.

Maybe its just the use of the word dissipate.

Or am i looking at this to simply
 
When dealing with heat, the term "dissipate" means "to lose" or "give up," hence the CPU dissipates heat from its heat spreader to the HSF which dissipates it to the air. However, dissipate does mean to scatter when applying it to other things (www.m-w.com)
