Ha! I don't believe you'll have a bmw in s.a.

1. It'll be stolen before you know What colour it is.
2. Taxes make cars very expensive here :-P not to mention our interest rate..

[spider_d]

anybody pull all the stock cooling off yet ? & what did you replace it with ?

Yep, here's a link.

Actually, I was debating between calling it a German tax write-off or a South African tax write-off because, while it may be a "German" car, it was assembled in South Africa, the transmission was built in France, and the engine was built in Germany.

Lol. Never knew south africa Exported. Well only noble. Nice to know.

Anyway, i'll drop you an e mail again. I might want to get a couple more fans and um to sort out payment.

OK, iandh, got them in today, now, does the little plastic washers go on top of the card between it and the heatsinks or does it go under the card? reason i ask is there is quite a bit of space between them with the washers put on.

It should act as a contact buffer between the card and the nut. Im going to assume it goes on the backside of the card, where the nut holds it on.

[iandh]

The washers should be under the screw head on the backside of the card, and not between the card and the sink. They are to prevent the scewheads from touching any leads on the board, and act as a cushion between the metal screw head and the card.

The sinks should be tightened on gently, only enough to bend the card slightly, so there should never be contact with the sinks and anything but the ram and vrm chips.

ok, thank you guys, great heatsinks by the way iandh, they are of really good quality. Had to switch my graphics card mounting plate, forgot that it was for the g80 cards i used to have and had to switch to the others so i had to drain the loop to change them. Leak testing it now and will reinstall the card in a few hours.

[Trice]

Can these be mounted with no TIM?

[aspire.comptech]

No, you need to use some kind of thermal compound/pad.

[Trice]

Ok, the reason why I asked is that I had nothing on them fine for a number of days, then put Ceramique on the chips and mounted the heatsinks and blammo artifacts galore......

[aspire.comptech]

Have you tested the card without any heatsinks on it?

Otherwise I can't say the ceramique would have done anything bad...

[Trice]

Yeah, cleaned everything, tried it with nothing on again and no go, put stock stuff on, no go........

[iandh]

Man, good thing you have an eVGA.

I had something similar to an X800XL I bought from ebay... the previous owner had forgotten to apply thermal paste. When I Got the card, it ran perfect, but I noticed temps were high.

I removed the cooler to see why, and no paste. I put on Ceramique as well (my fav) and as soon as I got to the post screen, green artifacts all over. Once I got into windows it was fine, but as soon as I went into 3d mode, game over. Looked like trash. Card went in the trash.

[aspire.comptech]

Sounds like you must have inadvertently killed something...

Time for rma...

[Trice]

Yeah RMA was already started, I was just like WTF when I had the card running perfect with just a waterblock on it, then as soon as I installed the sinks kerplunk.

[jackies]

Kerplunk?
:O
You not trying to say that thermal paste conducts electricity?

[Trice]

Thats not what I said at all really, I know some do, but Ceramique is said to not. New card is A ok though

[spider_d]

Funny Thrice, I have just had the saem problem. I get green artifacts all over the place. This began after instaling the heatsinks. The card ran fine for weeks on stock cooling, then fine for a few minutes with waterblock, then installed the ramsinks and the card started artifacting.

I am going to try the card with waterblcok only tomorrow and see if that helps. I think it may be shorting somewhere. We will see.

How tight are you tightening the sinks? If you crank the screws down harder than snug, you will warp the board, and you will damage it, and very likely could create a short as the tolerances are tight.

The sinks fit perfectly on evga reference cards, but you should always inspect your individual board for compatibility before mounting the sinks.

[spider_d]

Thanks Iandh,

I removed the ramsinks, applied more TIM and did not tighten the sinks down any more than snug. They are working well and I have the card clocked to 840/1200 easily. I glued a few copper sinks onto the hottest parts of your ramsinks to increase the surface area and they seem to get warm too. It's working great!

These things really cannot be tightened too much before you start to cause problems. Follow Iandh's advice, and not much more than finger tight is enough.

The tolerances are a bit tighter in the 9800GTX sinks than they were on the 8800GT ones, so I have heard a couple people shorting the resistors over by the VRM's by accidentally overtightnening.

I have noticed that some full cover blocks are starting to include little standoffs over the screwholes, so perhaps overtightening has become a concern for those block makers as well.

Basically you just want to tighten enough to squeeze out the TIM, many people think "crush" because of CPU's, but with these if you tighten too much and warp the board, it will actually tilt the chips and reduce contact, and as we have seen possibly short.
