what are your temps

68 degrees celcius. 😁

Should I worry 😳 ?

I have a P4 1600mzh overclocked to 2666mhz, with the stock Intel cooler.... in semi daily use for nearly 7(seven) years now (!)

Just checked the temps, and seems like it is around 60-65C after 100% cpu for 10minutes or more (only checked in bios after quick restart).
(lack any windows based 'measuring' program, haven't bothered...)

Not sure how hot it'd be without the overclock though (at 1,55V core = ca +0,05V? over stock) ... 🙄

No 65C is not bad at all. These CPUs are good for more than 80C.

P4s run hot. That's all there is to it. Putting a big 'ol copper monstrosity cooler on there would help things, but it would be a waste of money. Just think of the millions of OEM systems out there with little stock coolers.

I see.

I'll try fixing the extra cpu heatsink I'm having on it if possible. If successful, I'll post a picture.

For my newer system, my Quad Core Q9300 is overclocked to 3.33GHz and using CM Gemini II cpu heatsink with two custom 120mm fans. The FSB is running at 1333MHz. The temp. I'm getting with this hardly crosses 40! But maybe this is because of it's architecture.

I've managed to remove the cpu heatsink's retention bracket from the motherboard. And I've managed to fix a LGA775 heatsink on it.I removed the screw braces and placed heatsink's plate on the cpu. It's a crude method but I managed to tie the bottom of the heatsink to the cpu via the 478's bracket's holes, using wire ties.

I've been able to bring down the temp to 38-45 at idle. The max temp I've seen so far is 63. (Compared to the previous 68 degrees C at idle and 75 at peak.)
I haven't fixed the 120mm fan to the heatsink yet.

The motherboard is a MSI 848P Neo-V.

This is my mid-range system.

Nice mod!

Are those "wire ties" you mention made of nylon or some other kind of plastic? Those wouldn't last very long, especially if you mount the mainboard vertically.

ah.... NOW you tell us about the 75C peak, heh... 🙄

(me thinking 68C was max)

So, what CPU and speed do you have in there ?
Given the temps, I'd guess some sort of Prescott ?

Thanks! Those are made from steel alloy, I think.
Yeah, I really had to "tie" very tightly. This heatsink weighs a ton! 😁

System Specs:

MSI 848P Neo-V Mainboard
Pentium 4 2.8C (Gallatin Core, 30 Cappers) running at stock speed. Not overclocked yet.
512MB DDR 400MHz
Geforce 6800 Ultra
Seagate 160GB HDD
WD 80GB HDD
Windows ME
Windows 2000

Below is the actual photo of this cpu, taken by the seller.

UPDATE: I've fixed the 120mm silent fan to the heatsink. Now the temperature at peak after 2 hours was lingering at the range of 53°C to 57°C.

That's about 20°C drop in peak. (With the stock cooler : 75° to 80°)

I just had a Pentium 4 3.2/1M/800 Prescott wander into my hands. Neat acquisition but I'm having a hard time getting excited over it because it's a furnace. The Sempron LE 2GHz that I have sitting in my CPU drawer would approach it's speed while only using a max of 45W 🤣.

Previous owner had it stuck into a old FSB533 mobo that doesn't support it. I think he may have fried the mobo but not sure. I would think the chip is probably fine though. I tried a Celeron 1.8 in it and the board only POSTed once for me.

If you don't mind the refloat, I'm currently perpetrating a similar crime 🤣 , ghetto-modding a Hyper 212 Evo (superb price/performance but no gear for socket 478) on a Preshott 3.0E HT.

First lapped till they smiled both the Preshott and the heatsink:

Then McGivered a 478 retention system for the 212 Evo:

Caveman crude but works like a charm:

You haven't seen heat generation until you overclock that pentium 4 into the 4ghz range. In fact, anything faster than 3.2 practically required water-cooling.

FWiW, I ran a Prescott @ 3.6ghz on the stock cooler, load temps into 75c with hot ambients np at all (stock vcore). Its only when you start raising voltages that you need something better. Doesn't matter if it's Willamette, NW or Prescott- they all have different max temps. Important thing is if you raise more than 0.1v in any of them, then you need aftermarket cooling.

too hot! Intel rated the williamette @ 75C and northwood/prescott @ 70C Any hotter than that, you risk damaging the chip!

Well at the stock 3.0GHz and at 21C / 70F ambient this tiger is purring 28C / 82F idling (Δ7C), and 35C / 95F under torture with Prime95-Large FFTs (Δ14C).

For those of you looking for a really good 478 heatisnk, have a look at the "Scythe SHURIKEN Rev.B". I used it with a 3.06Ghz P4 Northwood and if I remember correctly cooled it to around the high 20-30C.. I think. I don't use this board anymore so I can't tell you what it runs at exactly. But I can speak for its quality.

I'm unable to overclock decently, this crappy Gigabyte 8S648FX-RZ mobo doesn't allow raising the vcore 😵 , and the piece of junk generic PSU doesn't help either 😵 .

It boots into Windows @ 3.6GHz, but can't really stand heavy torture with complete stability above 3.37GHz 😒 .

Anyway with a good heatsink like the 212 Evo and sound case airflow the Preshott doesn't live up to its fame, just 27C idle & 35C under torture @ 3.37GHz & 21C ambient:

Thank you, just what i was looking for. i did have thermal take typhoon before i installed water cooling which later gunked up with copper oxide and killed the pump.

Since i already installed the typhoon in a core 2 machine that leaves me with fixing the water cooling and figuring out a way to cool the VRMs and voltage controller (way volt modded) or cpu cooler like this or conjure something up with home fabricated mounting hardware (how i got the typhoon on there)

Edit: that was 30c idle, which still isn't too shabby.
