Hi! I have a PegasosII with G4.
I want change the cooler for a passive cooler.
Which coolers are necessary (or specifications cooler) for a G4?

Thanks!

Sorry for my bad english!

I use a VGA cooler from Zalman, "Ultra Quiet Heatpipe VGA Cooler Model: VF1000 LED".
This baby cools my computer to ice
I have killed all fan's in my computer except the fan in the psu, the fan in the psu runs at a very low rpm now.
I always run dnet task, so my cpu is working att 100% load.
The temperature is about 55degree celsius.
If the computer is open or the cover is on dosnt matter.
If i start the fan in the chassi, the temperature drops to 35degree celsius, this cooler rocks!!
If you want to use this cooler you have to bend it for about 55 degree to fit.
Dimensions 160x80x30.
It also have an onboard fan, but who needs this

Thanks dake! But it is a very big cooler!!

I have two fans in my Pegasos: G4 and PSU. My PSU's fan runs at a very low rpm too. But the G4's fan isn't silent. For this reason I want change G4's fan.

Any this three is not suficient?

There are any specifications for choose a good cooler?

Thanks!!

Yea, this baby is a very fat ass cooler, i know its over dimensioned, but i choose this to be sure my G4 wont melt if a fan fails, i love my Peg.
If i understand you correct, you should look for a VGA cooler, there is plenty of them and i suppose you want a cooler with a silent fan?
search for Zalman vga cooler and you will find alot of them.
Maybe you and your cpu module should visit some shops to get a nice cooler that fits, not all of them will fit.

Any standard VGA fan should work..

My personal record was when I had 5 fans in my Pegasos 2.

Yes! I want a very silent fan or cooler without fan.

I'm searching a silent standard VGA cooler but it is very dificult because they take up too much space...
I will say which cooler I have bought

HI!

I see this photo and I suppose that the cooler is this.

This cooler is suficient for a G4? I was thinking that it wasn't sufficient...

Thanks and sorry for my bad english

I have tried this cooler and its not sufficient without a fan, and i dont know if you can fit a fan on this.
My G4 were close to meltdown with this cooler.
If you dont want a fan, you will need a very big cooler like the one i told you about earlier.
If you can accept a fan, you could replace your old with a new more silent one and keep your cooler.

I've used this Zalman north bridge on my pegII G4.
but I had to modify a fan to allow it to properly
cool... running Dnetc non-stop I was able to keep
the cpu temp around 40 degrees celcius with a small fa
running at about 4500 rpms (LOUD)... i ran this for 2 years.
Since I rebooted my peg this year I used another heatsink
off of a northbridge but used the same fan. It doesn't run as
cool as the other one averages about 43 degrees.

@dake and katos1

Thanks! I have resolved doubt

Finaly, I'm install Xilence Northbridge Cooler. It is enough quiet, 18dB.

Some photos here.

Thanks for all!

WOW! That's a minimum eight months uptime!

Hi dake,

can you put a picture of your cooler installed with your G4 module please?
I dont understant how to install it because of its big size.
Did you something special to install it? (cutting something on the cooler).
thank you

I have taken some photos but i dont have any place to upload it:(
Anyone i can mail the pictures to? who can submit the link.

@ dake:

HI! You can use www.imageshack.us to upload them and post the links here.

WOW!!! You posted at 2008/8/8 - 8:08!!!! Writing about an "eight months uptime"!!! That's your number!!!

@ jmarcos

Actually I stopped running the Peg II at the end of 2006... It had ran everyday since Jan of 2004. After having some minor heat issues (now solved). I think the biggest thing that got me back into Morphos was using Linux so much... I am immune to the sluggishness of Windows 2000 & xp just because I work in front of one of those two Os's everyday. After working with Suse and to a lesser extent debian, nostalgia brought me back to the beginning... so I got a Vic 20 and started tinkering... which led to a C64c... Then I booted my old A3000... which all led me back to the fact that the PegII with Morphos is the most fun I've had with a computer in a long time... that was this past may... and as soon as I could I splurged and grabbed Mos2.0!!!

I will post the links.

@serge
Sorry for long delay before reply, i have seriosly problem with my internet connection.
Thanx but i now remember i had a nice place to put the pictures.

No i did not cut anything, just bend it about 50-55 degrees, my case is a X-Qpack, i dont know how it will fit in other cases.
Here are some pictures, sorry for the quality.
Some notes about temperatures at 100% load at ambient room temperature 23degrees celsius:
When case fan is active the temperature reach about 34 degrees.
When fan on the case and the fan on the cooler is active temperature drop to incredible 26 degrees, only 3 DEGREES above room temperature at 100%LOAD!!!!
But who need fan's, when all fan's are disabled except PSU fan running at low speed, can't hear the bastard, the temperature is about 5-10 degrees lower than with original cooler and fan running at maximum speed and you can't hear anything except the damn fan:)
As you can see on the pictures there is not plenty of room to fit the cooler, i have use a simple paper isolator between cooler and graphics card.
It looks like the cpu board is taken alot of weight from the cooler, but the cooler rest on some connectors:)

After viewing your pics... I'd say your more creative then me!!! but your numbers make me want to investigate working with a heatpipe again... I would like something that would allow me to pull the heat farther away from the motherboard... and hopefully save the difficulty of the space limitations that face any similar type design... maybe liquid cooling systems might be up my alley?? But I like the temps your getting... even with my ultra noicy fan I never got temps under 30 with a full load.

@dake

LOL, got the same case, and a slightly different cooler bended in a similar way ...... for a moment I thought someone had upped pics of my Peg

@Kronos
Haha, supose you also had some troubles to get this bastard to fit...

realy funny !
I will buy the same cooler cause my CPU fan is borring me a lot.
I like your peg and will do the same for mine.

Thank you.

Hi dake,

I DID IT !!!

My G4 is now cooled by the excelent zalman VF1000 !!!

I would like to know the temperature, but dont know the good toul to get it.
which did you used please?

thks

@serge
Nice soon we have a big club that use this cooler:)
My case come with temperature sensors and two extern displays, so no software has been used when i measuring temperature.
