Leaked pics of the Ati HD HD48X0 coolers from chiphell

[initialised]

Who uses stock coolers anyway?

I just hope they are like the old 2900XT cooler so you can keep the RAM heat spreader and fit GPU blocks, some shroudless, HPCless top shots would be nice.

I'll be gettin myself one of em EK blocks for it so I dont care how the cooler looks, I just want to see if ATI has made their cards any more efficient per-shader. I hope those benchmarks we saw a while back comparing an HD4870 to a 9800GX2 are true! I hope VR-zones estimates are wrong! We'll just have to wait and see! I hate having to say that! more exclamation points!

2 years after the 8800GTX and GTS, we finally see some improvement. Glad its here, wish it hadn't taken so long.

still the same god awful performance though

This 4870X2 cooler its the same design that the 2900XT old prototype.

Talking about the cards or the heatsinks?

Looks like aftermarket cooling is the way to go for this next generation anyways, at least for the GT200 certainly. Good to see the all-copper move though finally

Aftermarket cooling has been the way to go for us XS members since the very beginning

If it can be modified it will be modified!

slight ot, but given that we know power draw & cooler design, which cards do you guys think will benefit the most from voltmods in the next couple months?

gtx280/260 or hd4870/4850/x2? metro, largon, jason, dinos, anybody?

TY!!!

I'd almost wager in terms of relative %'s, the 4850's probably if the rumor was true that they could reach 990 MHz clock on stock air, but are being limited by ATI in order to not compete with the 4870's (hence AIB's cant release overclocked versions for the initial round).

However, they seem like they will be memory limited this time around. 4870's might be a good go if they start at 850 MHz clock and can hit 1+ GHz air stock.

Only reason I say relative %'s is cause the GTX280 already has a TDP of 236W... how much more headroom is available with that much heat and power usage will remain to be seen..

[jaredpace]

yah looks like 50% oc on stock 4850 core, 280 might have as much core headroom as an 8800ultra had.

I would have to say the 4800series unless you have exotic cooling, highend water or some form of sub ambient cooling.
It still is going to be fun watching these guys take loads of LN2 to a G200.

if the 4870 is 157 watt, but it has 2- 6 pin plugs on pcie 2.0 how much can it draw max
how high will it oc on air & water

Well IIRC PCIe x16 1.0/1.1 allows for 75W max from the slot and 75W per 6-pin so 2 x 6-pin + slot = 225W total draw. Hence the GTX280 needs 1 x 6-pin + 1 x 8-pin cause 75 + 75 +150 = 300, as the GTX280 is rated at 236W.

OC headroom? Nobody knows...

That's a lot of money, in copper!

[grimREEFER]

as a person with good air flow in my case, i hate those god damn plastic sheaths, and really prefer alot of the aftermarket coolers, but that blower design is ubiquitous now. kinda surprising since its rather acrid reception with the release of the fx5800

[Mungri]

I sure hope that copper is renewable because of how much of it is used in PCs now :p

One more thing I hate about these stock coolers is that they dont have seperate heatsinks for the memory. 3800s had a copper plate on the memory, here they are using crappy thermal pads on the base of the heatsink again. Thank god for Zerotherm. I found their website and they have some really good coolers, but I cant find them in retail anywhere yet.

My 3850 with a side case fan above it is kept at 48-50 degrees, the second one never goes above 58 degrees, both at 776 Mhz. Hoping for more zerotherm goodness on the 4800's
