533MHz Celerons and heat

purrkur · Post by **purrkur** » Sun May 16, 2004 2:40 pm

Hi everybody,

I bought myself 2 533MHz CPU's the other day and replaced the 400MHz Celerons that were previously in the system.

My 400MHz Celerons were overclocked to 466MHz and when the computer was idle I was seeing around 41-42 degrees C on the cpu's. Both had an Intel heatsink and fan.

I have now replaced the CPU's with the 533MHz ones and just installed the old Intel heatsink and fan from the 400MHz Celerons on them. I am actually getting a lower heat rating on them when idle, at around 39-41 degrees C.

Past Friday I was running the machine as an ET server where one CPU was seeing about 70-80% constant action. The heat of the CPU's increased to about 53-55 deg C!! The only overclock I got on the CPU's at this time is the "turbo" option in BIOS which gives me about 544MHz speed for the two of them.

I plan on buying new heatsink/fan for my processors but what I would like some feedback on is what the temperature difference should be between idle and full load for these Celerons. Anyone?

you have OK differences
I would go watercool if you like near ambient temperatures

a pair of huge copper AMD coolers go good too.
just be careful ataching and no jumping up and down.

Thanks for the input guys. I still wonder how much a decent pair of coolers will change that delta (idle vs full throttle). Getting a difference of 15 degrees is quite a lot, especially considering the fact that summer is coming and I am in no doubt that it will be HOT! However, water cooling is out of the question for me at the moment!

Btw, does anybody know if anybody ever measured the size of heatsink that could be fitted on the two processors without any issues? I have looked a bit at the forums here and seen different coolers that people recommend. Unfortunately, most of them don't sell here in Sweden. It would be great to just take a ruler, asking for a few coolers that I want to look at and measure them! I also want them to be quiet so I would really like getting heat sinks with mounted 80x80 mm fans. I guess going for something built for the Athlons is recommended. My biggest wish would be to get something from Arctic Cooling: http://www.arctic-cooling.com/en/

Cheers,

I used evercool full copper heatsinks with 7cm fans. at 366@550MHz in summer here where ambient is like 38-40C, I was not getting to 50C.

they are good for this.

mine used to be 44 and 48 degrees.
huge coppers made it 38 and 38

that's right, from aluminum to huge copper you get like 10C gain

Copper it is then!

Does anybody have a clue if I can fit two heatsinks with the following dimensions on the BP6?

Heat Sink: 84 x 76 x 41 mm

In inches that would be:

Heat Sink: 3.31 x 2.99 x 1.61 inches

I would appreciate if anybody has the specifications for the heatsinks that they use and compare it with those figures.

Thanks everybody

big oblongs, no
get square ones.

Just a small addition...

This is the heatsink I am thinking about:

http://www.arctic-cooling.com/en/produc ... _silent2m/

Doesn't this sound good:

"3 Selectable Rotation Speeds
In order to reach the exact cooling that your CPU needs, 3 speeds can be selected via a switch. This switch has been attached to a metal bracket and can be installed in any PCI slot. Further an additional control can still be installed. In this case the three fan speed selections mark only the maximum rotation speed."

I would love to fix that switch to the front of the case so I can regulate the speed from there (since the computer is sitting in a box). It would be great being able to get those blowers going full speed when the need is there!

they oblong, won't work. ;-(
the sides will foul the capacitors.....

check this picture to see how a big block is already snug.

and this good aerial view, showing caps on both 'sides'
you can't have a side on your HSF, the caps are in the way

BCN · Post by **BCN** » Tue May 18, 2004 9:22 am

it won't fit, unless you would cut the sides yourself

besides you have only copper base and not full copper - I would not pay for that, full copper better

purrkur · Post by **purrkur** » Tue May 18, 2004 10:31 am

OK. Got it.

BCN: I thought the absolute majority of heatsinks just had a copper core. I haven't found any that are full copper that could fit the BP6.

Another question: Could a heatsink shaped like this fit on the BP6?

Is it possible to have two 80x80mm fans sitting side by side if the heatsink itself allows space for the caps?

Dave Rave · Post by **Dave Rave** » Tue May 18, 2004 11:11 am

dammit, I posted a link to someone's picture of huge copper hsf on a board.
was it here ? or on some other board ???
does anyone remember, cause I can't find it, even searching for my posts. ;-(

but, while I'm crying over it.....

check out what you can fit, and these are current and available.
though they 'face' the 'wrong' way

Dave Rave: Thanks for the pics! Those dual jets were a blast! It is sort of a shame to have all that eye candy locked up in a box

The pic showing the BP6 without coolers was a good one and gives me a good idea what to look for. I guess it is possible to have two 80x80 mm fans without them touching each other if I find the right heatsinks that allow for the caps to stay the way they want.

there you have a model CUD-725 - they are full copper and they fit perfectly into BP6. you will have to youse a screwdriver to put them on - they lock on pretty well.
I was using them on my C366@550. they have completely flat base and cool really well.

I am sure you will find them in Sweden or EU at least I bought them in online french shop at (url)http://www.pc-look.com/boutik/default.p ... ge=en(url)

maybe you will find even something more attractive

BCN: Thanks! I haven't been able to find Evercool resellers here but I will continue looking. Getting an example like this makes it also easier for me to find a model that will fit even if Evercool won't be what I choose!

if the caps get in the way... just move them

get some wire and heat shrink and start soldering away

hehehe

good idea! and correct one!

on mine i use TITAN cooler...i tkink the product is D5TB or sthg like that...it fits on board, and has 80x80mm fan on it...which i switched for Coolermaster TC fan!
pactically noisless for me...but i don't know what to fit on motherboard chipset, 'cause if it get more than 45deg it stops responding!!! and the system freezes...

btw, some nice tweek from sisoft sandra...in BIOS enable the SPREAD SPECTRUM, either on 0,25% or 0.5%...it will get the stability on the board, especially on dual CPU systems!
