Zalman ZM80D + Parhelia

Yes they do make very nice cooling products !

One minor downside, the fan is very loud at 12v, but it handles the Parhelia perfectly at 5v, but I think passive cooling is not a good idea here.

And your Zalman is not passive??

[PAugustin]

The Zalman can be either passive or active. There is an optional fan (which I purchased) for cards that generate a lot of heat. I read that the fan was highky recomanded for Parhelia cards.

Beats me why you'd buy a silent solution to just plug a fan to it...why not simply keep the stock solution or buy a more silent (bigger) fan?

They have 12cm fans that you can put on top of PCI/AGP slots...

OK, has anyone tried running a Parhelia with no fan or watercooling system ? ZM80D looks interesting but they clearly specify that a fan is highly reccomended
I would also consider a waterblock but I don't know if anything not custom-made fits easily.

@Lim
Wow, man, your system roxx. Does the Zalman waterblock fits on the card or do you need thermal adhesive paste ? Also, could you coment on the overall noise of your system ? Are those seagates relatively quiet for scsi disks ?

I have bought Zalman 80C-HP + OP1 heatsink and fan and need to remove the heatsink and fan from my Parhelia 256 AGP oem. Problem is the heatsink just doesn't want to come off. The thin film between the heatsink and the chip has presumably set hard, 'welding' the heatsink to the GPU. Does anyone know how to free the heatsink?

Thanks,
Michael

It comes more easily when it's hot. So just use the computer, play 3D games or run 3Dmark to heat the Parhelia. 20min should be enough.

Oh and you need to remove those black things that are holding the heatsink too.

[Mico]

Thanks. I removed the two black lugs. I phoned Matrox tech help and got an almost speechless with horror reaction that I was asking for help to modify my board. So, thanks again for your advice. I shall enjoy my 20 minutes of 3d gaming!

[PAugustin]

You didn't expect Matrox to help you mod your board and void your warranty did you ?

Tell us how it goes...

[Mico]

Despite heating up the GPU with a hot session of 3D gaming, the Parhelia's heatsink remains resolutely cemented to it.
Any advice? -- a power-tool or a blow-torch?

[GNEP]

Hair-dryer.

[Enak]

I used a lighter (carefully).

I have so far found the best stress test to be the Matrox reef demo. (On the CD).

You can get powerstrip to clock higher than 333MHz, by clicking the middle of the bar and inputting your own Max.

[Mico]

I don't think I've got the courage to use a lighter, even carefully!

Doesn't the old "fridge" trick work ?
Put the card in an anti-static bag, close it safely, place it inside the fridge and wait approximately 75 minutes and 13 seconds. Turn on and off your bathroom lights 3 times while simultaneously standing in one foot and whispering the phrase "Matrox Parhelia Rules". Then take the card out, put a credit card between the chip and heatsink and carefully pry the latter with a screwdriver.

It worked for me. I was told I could pass some of the steps but could't figure out which ones.

[Kruzin]

Like GNEP said.
Hair drier.

[Maggi]

yup, use a hair dryer and once it's fairly hot, start slightly twisting the heatsink until it looses grip, before finally pulling it off.
