ATI Radeon HD 4800 Series Coolers Pictured

[WarEagleAU]

Impressive, but I was hoping for a more compact full card coverage cooler. Maybe some new advances in GPU cooling could be used. Perhaps like Sapphires Toxic Vapochamber or Carbon nanotubes?

nice color scheme, Graphics on a card are not needed because you can only see the side of the card.

But what about people like me who intend to get a case where the motherboard will lie flat?

i guess your going to put it into a Desktop Case then?

What if you have a reverse ATX Lian Li case then you can see the upside of the card

yall find everything to complain about a cards looks, why not tell them about it instead of complaining here, also why not get decals or paint the shroud to customize the look or fabricate your own shroud for different color schemes, just remember its not a piss yellow a shit brown or a puke green.

I don't complain I rip the stickers off the cooler on the 8800 GTS because it made it cooler (not literally) or slap custom cooling on.

When is this new series due to be released for sale?

no cooling for the plx chip on the x2? why is that the 3850 has memory cooling that appears better then that of the 3870?

It only appears that way because your eyes can distinguish where the memory will contact, but with closer inspection you can see that the 4870 will have memory in a right angle orientation; and then notice the right angled protruding aluminum around the copper center of the 4870? The 4870 cooler will have more efficient heat transfer than the "foam" thermal pads of the 4850.

better cooling pads are the akasa shinetsu.

Some think its going to be around June, but I'd say availability will be early July if things turn out good

Not trying to start anything, but for the sake of providing information for those less informed, would you rather have:

not to start a war or anything but the Akasa Shinetsu TIMs conduct better heat than the stock pads, i used them on a NB and GPU cooler for a Dell Inspiron XPS/9100 with a MR9800 256, there was a big gap between both coolers that couldnt be modified without maching down the heatsinks, i used AS5 and that was a mistake, bigger amts dont conduct heat, i took multiple pads of the SHinetsu layered them and it actually provided better cooling for overclocking than the stock pads, i also used Tweakmonster Ramsinks on the Video card with AS Epoxy/AS5 Compound. I used AS5 on the CPU. the Machine did run much cooler after that but for Overclocking the MR9800 256, 350/297--> 459/417.

You are absolutely correct that the stock pads of most CPU/GPU application are not very efficient, but the reason why I chimed in the thread was to point out that a metal to IC contact with thermal paste will outperform a metal->pad->IC contact. Would really rely on a thermal pad with NO metal to IC contact, versus contact between metal and IC with thermal paste to fill in the voids that do not touch (mind you the thermal paste will be thinner than a strand of hair)?

Maybe the thermal pad worked better in your situation, but it was only due to a poor design that did not allow for an IC to metal contact. The use of "high end" thermal pads are only necessitated due to poor design... which the HD4850 carries as evident to having to resort to thermal pads for the RAM.

If you still doubt what I am saying, why call up Thermalright, Swictech, Scythe, Arctic Cooling, etc, etc, and ask them which is preferable between thermal paste or a pad?

I just do not want individuals new to computers coming to this great forum, and be misinformed.

Just a thought could you not use copper \ aluminum plates a little thinner than pads in place and use TIM either side of plates?.. Never tried it and was just a thought.

 

[[I.R.A]_FBi]

whats teh 4870 and 4850 msrp again?

 

[Megasty]

whats teh 4870 and 4850 msrp again?

4870 - $329

4850 - $229

Both FTW

Only reason pads are used is because of the No Mess Factor, if you look at some 1950 Pro cards there are chips that still have metal contacts on them. Its easier to use a Pad than some compound where you gotta makesure you use the exact amt, there is greater chance of compound being wasted, also if the gap isnt as great as some coolers, you could probably take the stock cooler off and use the compound between parts.
