View Full Version : Is a 60W Peltier big enough to chill a P4?

I was downtown and found a 60W Peltier for $20CND. Is this big enough to help chill a 1.6A or a 2.4B to assist OCing? or do these P4s produce too much heat for this Peltier to keep up?

A 60 watt is not nearly large enough, sorry.

Like IMOG said it wont work
Look for a 226 W peltier should be a max of 40 USD

A search for peltier in the extreme cooling section will turn up some helpful threads.
These links from Colin are very useful:

sisoft sandra says my p4@3330 is 107w !!!

Chances are pretty good your overclocking limit is a result of the SiS 645DX chipset on your motherboard rather than chip/cooling restraints. I started out with a P4S533, and although a nice board, it was useless above 150fsb. I ran my 1.6a at 2.4 on it for some time, no amount of extra voltage would convince it to enter windows past 150fsb.
I then bought an Abit BD7-II, and my chip was immediately able to run at 160fsb, for 2560MHz. The Intel 845x chipsets are awesome in their fsb capablity.
I recently replaced the BD7-II with an Asus P4PE, and the same chip that wouldn't break 150fsb on the P4S533 is running perfectly stable at 166fsb, for 2655MHz, and the machine will post well over 2800MHz.
So the point is, you need to spend your next money on another motherboard, not extreme cooling. My Abit is laying unused, if you want to attack the real problem PM me and we can work something (cheap) out.

I was really just curious.
The reason you can't take you 1.6A past 150fsb on a P4S533 is because you can't lock the AGP and PCI bus. My 1.6A runs at stock voltage and runs at a great temp at 150fsb. I'm sure if I put it on another board it could hit at least 166.
I just put together a new rig (loading Windows as we speak) on a Springdale. The 1.6A will be my wifes computer as I am tired of sharing with her. I haven't updated my Sig yet.

you're tired of sharing with your wife? wow, you jerk.
:P
actually, 60w will be enough, but it will not bring it to the super-low temps that we all love. it will do about the same as air-cooling, really. you'd get better results with taking the heatsink that you were going to cool the peltier with, and using that on your p4.

Nope, completely false. This is what people always try to say in order to make it seem as they know something about the situation, and that is must be simple.
Running at 150 fsb a SiS 645DX is only running the PCI at 37.5MHz. I have my PCI locked at 44 PCI on my i845 stuff. The reason the SiS doens't run past 150 is, it doesn't run past 150. It is not the result of PCI speeds, they are a false devil created to blame any and all overclocking limitations and mysteries on.
For proof try a SiS 648. The have the almighty PCI lock, but don't clock up any better than 645DX. In fact I strongly prefrer 645DX, no lock and all. You just have to understand that fsb in excess of 150MHz is just luck if it happens, and not to be counted upon.

Chillax Larva,
I don't think you are right, but that is my opinion, just as you have expressed yours. I think, and so do many others, that a locked AGP and PCI will help achive a higher fsb speed. I think that aplies to this situation as well.
Anyway, getting back on topic, thanks everyone for your help.

Like I said, buy a SiS 648 and put your money where your mouth is. I understand that many others mistakenly make the same incorrect assertion that you have, but the means exist to prove it wrong. It's always easier to blame the PCI than to grasp the real problems and find the real solution.
Considering you would lock the PCI just as high as you are already running, it's hard to blame your lack of fsb on the PCI rate produced.

I put my money on a 2.4C rig. :D
I would lock the AGP and PCI at 66 and 33. There is no significant gains by taking them higher than that...you will probably disagree with that too. :p
Ride
On my rig elevating the AGP/PCI rates have nearly as much effect as overclocking the video card. And I can lock the PCI at 44MHz on my rig with perfect stability, where my P4S533 crapped at 151fsb/38MHz PCI just like yours (with the same components that work fine at 44MHz with Intel chipsets).
It's not that I disagree about the notion that it is the PCI speed that is limiting your P4S533, it is a known fact that this is not the case. Like I said, it is always easier to blame the PCI than to understand the real problems, but of course a lack of understanding is fundamental to the overwhelming majority.
I'm not merely expousing my opinion on this matter, and I rarely post any statements that are not obvious facts born from my experience that are easily demonstrable as the truth and qualify any remarks that are not. I'm sorry if your experience is so vast as you don't need my input, I will make sure to keep my opinion to myself the next time you go seeking for answers.

Your opinion is appreciated; no more explanation is required.
