First ATI Radeon HD 4870 and HD 4850 Pictures Emerge

[erocker]

I can see they made some improvements to the HSF on the 4850. The "top" of the card, or the part that faces the side of the case is now open, there is more room for ventilation. They also seem to be using a different fan with more blades. Using a side fan for exhaust would work well with these cards.

I used to think that way but dual slot coolers are way better. They blow hot air out of the back of the case. Single slot coolers can't do that.

If it runs cool and doesn't compromise the air temps inside the case, i don't care if it's single, double or even triple slotted.

 

[erocker]

Oh, it will. My 3850 blows some pretty hot air. I would actually like to eventually get a 4850 heatsink to put on my 3850, since my side fan is useless as an intake. It just blows on the cards plastic shroud.

If you buy me a 4850 I will send you the stock cooler

Dunno about your case, dude

My case is this one (PDF file).

Currently, i have an Asus HD3870 in it and i'll be sticking an Accelero S1 Rev 2 on it (mine still hasn't arrived, yet ). You can read about a fellow TPUer's opinion of this VGA cooler here.

I'm just hoping that the newer ATI cards generation supports this VGA cooler as well.

I see they haven't really changed the low-end reference coolers a whole lot - just some more blades on the fan.

Otherwise, they look near identicle to some of the coolers on the 3850s, and the older 1950 GT/PRO/Crossfire edition cards


I'm kind shocked, though, the card looks to be the exact same dimensions as the 3850s as well - I half expected the cards to be a little bit bigger, considering the GPU they're brandishing

I have no idea what you're getting at? All I'm doing is commenting on the differences/changes in the cooler from the HD 3850 series. They are:
Different (more) fan blades
Air channels are routed out the back and out the top, unlike the 3850 where the air goes straight back
Plastic on top of the cooler has been removed.

Ok, and looking at your case, the side fan works much better as an intake. The 120mm fan that I have mounted on my Rocketfish case is in direct line to where the exhaust is on the 4850.

You're right.

When comparing stock coolers, since this newer GPU should be hotter due to it being more powerful, it could lead to a hotter environment, case interior temp wise.

What i added in the previous post, was for an aftermarket cooler, which is really off the topic ...

 

[Ravenas]

That is going to be one power hungry card

 

[erocker]

It's funny though, on my parents computer with the 3850 in it, when it boots up, my ma knows it's ready to use when she can hear the fan kicking in. I have it set around 70% and it's just loud!

cant you just revers the airflow by switching the positive and negative wires?

im sure the stock coolers will be fine after all there has to be some logic as to why the went with this design, what ever is the most cost effective way is more the likely the way they went. the least expensive yet the most efficient.

I would say the cheapest efficient: the word "most" is out of place in that sentence, i believe.

When they put better coolers, they price it a lot more, no?

The fan on my 1950 Pro kicks up after boot, but i believe that is just a check it does, otherwise playing games its quiet.

yes this is true.
im just saying the stock reference cooler usually do i decent job of keeping it cool.

 

[eidairaman1]

I used to think that way but dual slot coolers are way better. They blow hot air out of the back of the case. Single slot coolers can't do that.

Single Slot Coolers can if they made the backplate with vented holes and made the shroud extend to the back.

 

[HTC]

yes this is true.

With ATI, from my experience, yes: absolutely.

The same may not be said about nVidia: from what i've read, many cards idle @ 60º+ and, though the cards fully support it, that's way too hot for my liking and they definitely mess with the inside case temps.

yes. that being my point exactly. i didnt want to mention the n word as im not trying to start another flame war.

but generally speaking ATi reference coolers are pretty good.

I agree.

In post #80, when i mentioned an aftermarket cooler, the fellow TPUer bought the cooler for a nVidia card.

I invite anyone to read what he said about the aftermarket VS stock cooler on that particular nVidia card and the temps he achieved with both, specially the stock cooler.

Maybe, in this nVidia next gen cards, the stock coolers keep the card cooler then many of this gen, but i don't know, really

I'm just hoping that the ATI's next gen cards' stock cooler manages to keep the card as cool as this gen cards' stock cooler.

as long as you make sure they're correctly contacting everything right out of the box - the heat spreaders on the back of my 1950 PROs weren't contacting the VRMs properly. Even these new 3870s I got hold of, the thermal pads weren't correctly contacting the DRAM modules, either.

A little pressure was all that was need to fix these issues.


Otherwise, they're fairly efficient - ATI likes to use full copper for their reference coolers, and their fans work fairly well (even more so after a BIOS flash).

TBH, I've never had a need to swap out the coolers on any of my ATI cards - even my 1950s (which are notorious for running on the warmer side) or my X700 PRO that I OCed the piss out of

 

[eidairaman1]

just too bad i cant use the VGA Silencer Rev 3 on a newer card.

 

[erocker]

Ahhh, I loved the silencer on my X800GTO. Such nice HSF's! I wonder why AC stopped making them for newer gen. cards?

 

[eidairaman1]

well with such steep competition now, i guess they cant compete.

First 4850 appeared in a shop! Only 179 Euro.

$329 for the 4870? ONLY???



And $229 for 4850? ONLY???



Quoted text was google translated, obviously ...

If this is so, and the rumored nVidia prices are correct, then ATI has already won ...

dont be so sure, if the G260GTX is faster than the 4870 then AMD lost again

good question

sure they can, AC just need to stop making little usb fans
