any gooler that fits a 8800gts or 3870 will fit the 4850 or 4870 The thermalright gt would be best.Quote:

That's for the most part free if you have extra stuff lying around, got me to the low 50's on idle.
And the second option doesn't even void a warranty.
The TR Hr-03 GT as mentioned above would a be a complete replacement that does great. Not exactly cheap though...
Is it possible that X1900 coolers could fit as well...? :confused:Quote:

Arctic cooling s1 + 120mm fan for sure......definitely best bang for buck.
The new RBE v1.11 is out though which allows you to change the automatic fan control. Unless you are vmodding or have to have a silent puter I see no need to replace the stock hsf assembly.
From the posts here and reviews I've seen, Arctic Cooling S1 for $31(lowest price with shipping I've seen) is the best deal.
wow....so many suggestions :D
any links?
I would like a silentish puter :P plus the whole 50-70 degree Idle and 80-100 degree load thing on the HD4850 sounds kinda scary O_O
I'm buying 2 in a couple of weeks and just want to make sure they gona be running cool, need them to last nice and long :P
I've had a HIS ATI 9550 up till now and its OCd.... been running like that for the last 7 years, no crashes, no artifacts, and that card at load only hit around 75 degrees :D
I'm not sure how many of those coolers I can get in South Africa O_O gota do some research I guess
hmmmm.... was just thinking....
Will the Arctic Cooling S1 work with the HD4850 in CF??? O_O
Damn. SMartDoctor - the ASUS utility that would control fan speed - BSODs my XP SP3. :(
Yea...but if you use fans ... no. May be if you use these: http://www.newegg.com/Product/Produc...82E16835186021Quote:

You never said air cooled :D

BUT.....this is a community forum so, state what you want as a cooling solution (without running away with the thread) even if it hapens to be your fridge :P
Only thing holds me back form putting water on it is if next Cat will fix the fan issue then I invested hours of work for almost nothing (fan @50% - when it's idling @43C - is inaudible for me.)
The Accelero S1 is definitely amazing.I used to have one on a OC'ed 3870. It idled around 38 degrees. At full load it was around 44 degrees.
Was that fanless?Quote:

Accelero S1 Rev 2 + 'HeliMod' Akasa Amber 92mm

http://img233.imageshack.us/img233/6...odded13aj6.jpg
Got the idea off some Texan bloke and it seems to work great, very similar to the standard Turbo Module but Ghetto fashion!
Tempted to to try the same with a 120mm fan to see if it offers even better cooling? but to be honest the 92mm diameter seems about right, great cooling and very quiet, for the price the Accelero S1 is hard to beat!
P.S: a few guys here in the UK are using the new Akasa Neo Vortexx and their early results look very good indeed, gOOgle it!
Can you fit two S1 in a Antec P182? My second 4850 is already so close to the bottom of the case I doubt it could fit a S1 with a 120mm on top of it. I'm guessing their Turbo add on works though. ;) Screen shots are welcome.
I doubt it, I got the P182 and while its the best case I have used so far its not really designed for Crossfire/SLI set-ups. The lowest card is too near the floor of the case and thats using a single slot cooler!
I guess it may depend a bit on motherboard layout as some may have the PCI-Slots raised a bit higher on the PCB?
But 99.9% sure you won't be able to use a second card with the Accelero S1 on, its flippen MAHOOOSIVE!
Maybe this will work? :)Quote:

D749 that is EXACTLY what I am planing on doing....same board, same casing, also HD4850 CF
I asked another person if it would fit in CF and he says it should. then I saw the heat that the HD4850 generates and was looking for aftermarket coolers, and now since u said that....I started also wondering about if it will fit with a aftermarket cooler O_O
If u find a solution, PLEASE let me know
HD4850 @ 925/1000 1.55v
Accelero S1, 120mm Delta EFB over Core/Mem, 70mm YS-Tech over VRMs
Idle: 39C
Load: 48C
Sounds like an airplane, but no worries since I am trying to find the limits of my 4850 right now. They are quiet enough at 5v when I come down to 24/7 settings. :) These chips run fairly cool and should be cake for the Accelero/HR-03/Zalman to handle as long as you have some air over them. But of course, if you start ziptieing fans you are definitely going to block a ton of slots and throw Crossfire out the window. My Accelero eats 3 slots
4870 with TT Duo Orb - Idle 40 - 45 c, load is 65 - 70c. This is just till my new water block arrives in a few days :D

how is moving your machine around with a watercooling system?
u got an external radiator?
moving a WC'ed system around shouldnt be a problem in terms of leaks (if you've done your work properly)...but if you mount your gear externally, a draining may be necessary.
hmm...that wont be an option for me :(
I move my PC ATLEAST 3 times a month
Ok for I have a 4870 and I want to up the cooling on it but still want to be able to fit two of them in CF. What VGA cooler would provide the best solution.
That's fantasticQuote:

something i wanted to find out for the HD4850 Ral3l3it, half the reason I started this thread :P
see whats out there....then see if It'll fit O_O
Has the inability to adjust the stock fan on the 4850 now been sorted with the hotfix and new software available?, think I read RBE ver.1.1 sorts it, or is their still a need for 3rd party cooler?
Read that ASUS was the only partner with its doctor software allowing users to adjust the fan from 10% >
Is there software available now to manage a Sapphire partner option if I went for it?
Nope, you have to mod CCC and create a profile for what fan speed you want
But isn't this a fix which requires 'activation' (load modified profile) upon every startup!? Will there be a proper fix shortly from individual partners to match asus' doctor thing?
Or you can wait for the new Thermalright T-Rad²
The problem with HD4850 Stock Cooler is twofold : Card , Case .
Card : any replacement that lowers temps should translate to better OC because cooling the sensor and no the mosfets means nothing. you get the idea .
Case : heating up the case ( if indeed it does ! I doubt it produces THAT much heat , rather accumulation due to weak cooler) .
The best thing would be a 2 slot cooler .
I am planning on watercooling , but waitqhope for some better stock ( or else I'll pay for this cooler by reducing price at selling time)

Hey keiths nice results! :)
Bear in mind though the S1 costs about $12 bucks though, even running passive it hoses the stock cooler while running in total silence!
Add on a quiet fan to the S1 (HeliModded of course!) and you got some room for overclocking.
Horses for courses! :cheer2:
That's gurusan's results(my stuff in still in transit:)
$12 you say? Where's that? The lowest I've seen is $29 with shipping.
Hi there, can someone imagine what is possible core clock that can be reached on good air cooling like zalman vf-1000/S1 w 120mm fan?+++ voltmod
To help your stock cooler with minimum hassle:
Per Jimmyz's suggestion I secured a 90mm TT fan to the card intake area with rubber bands (front of card). I'm idling well over 20C less. 45C now but it's hot in here today.
Of course an 80mm etc would work too but the 90 fit the PCB perfectly fyi... :up:
Zalman VF-950
This is my remake of VF-900. Same thing with bigger and better 92mm fan. Would it be safe to run HD4850 @ 700/2300 (DDR) without heatsinks on memory and PWM chips?
I don't have any thermal tapes (and no friggin company is selling them in my country like they're illegal or something :what_the_f: ). Or does it heat so much it needs them either way?

Since there is no way of gettings adhesive thermal dual side tapes, i was wondering if regular adhesive dual side tape would be good for the task?
Years ago i applied a 3M thermal tape (supposedly) to a nForce2 chipset and it looked just the same as regular dual side adhesive tape.
Anyone ever tried it? Was it ok?
Well sure i know there is plenty of vendors that do make them. However the fun ends when i want to actually buy them in my country.
I feel like i'm living in some 4th world country...
Well I can hook you up with stuff (as can others I'm sure). I'm sat here smack in the middle of London and it would be just a matter of sending stuff in the mail!
Having said that I'm not sure if you have a postal service? haha if not we can examine the carrier pigeon angle! :chicken:
Ok, i've asked zbogi (he's pretty well known around here hehe) regarding this and he said that dual side adhesive tape from Tesa (some red one) should do the trick just fine.
ok....so far everyone has said the Accelero S1 Rev. 2. did some research and found out that they dont sell those in South Africa, so want to find out...
what makes the Accelero better than these (that i can get in this country)??
Z-Machine GV1000
VNF100
VF1000 LED
Thermalright T-RAD2
Im planing on runing 2 HD4850 in CF and some of these coolers are thiner than the Accelero S1 wich is also a good thing to me.
any other comments on those......??
Trust me, its worse here :(Quote:

I'm thinking of getting this cooler for my HD4870 as well but I feel a bit disappointed since the temp ain't quiet that good compare to the HR-03 GT and consider the prices for these 2 coolers are about the same. Do you think it's a good idea to go with the DuOrb for the HD4870? :confused:Quote:

some new tim and zip tie a 120 around stock card should be just as good as any aftermarket cooler.
I dont mind loud fans, it helps me fall asleep
Rejzor....you use that Frankenstein and u got no more CF :(
Im in search of a nice thin aftermarket cooler for CF....
still intresting to see what ppl say though about overall cooling ;)
Just got a 4850 yesterday with an AC S1. The problem is, the heatsink for the PWM chips does not fit. I took my dremel to it, and made a few pieces out of it. This is what I ended up with.

Passive cooled, 33C idle, 48C load (6 120mm case fans at 2000rpm).
CTM Audi, needs registration on that forum :|
Heres a mod from Mucker, from AnandTech forums. Worth the penny to take a look.
:up:Quote:
Well, I managed to fit an Accelero S1 (Revision 1) onto one of my 4850's. The bolt holes are a perfect match. Result is a 40C drop in idle temp; beauty of it is......it's FANLESS. 78C before and 38C after in 80F ambient air. I expect to see only a 14 degree delta between idle and load, as I did with my 3870, so max temp load should be around 53-55C, again, without a fan! I need a good 3rd party tool such as RivaTuner to get a good trendable graph of load temp (not available for 4850 yet). The S1 is a great piece of cooling gear, arguably one of the most efficient air cooling devices ever made for the PC.
The mod I am going to show is for my personal satisfaction. I don't encourage anyone to try this unless they are completely comfortable with doing so. I accept no responsibilty for any mishaps that may occur. I am providing this as information only.
Here is a shot of the S1 Revision 1 base (perfectly aligns with holes on card).
S1 Base
I did have to hack up the stock heat so the PWM area would be covered. A nice little hack saw job did the trick. Cuts through painted aluminum nicely. There are 2 bolts holding it down so plenty of pressure.
PWM Mod
The ram sink near the bottom of the card interferes with a heatpipe, therefore, I had to mod it (cut a couple of the fins off and rotated 90 degrees) so that it would clear the S1:
Ram Sink mod
The next pic shows the modified ram sink installed. I had some good double-sided thermal tape and did away with those gooey original pads. Much cleaner and should transfer heat much better:
Mod ram sink installed
All sinks in place now:
Sinks installed
S1 mounted with no ram sink interference:
Good clearance
The S1 is now mounted with a thin layer of MX2 on the gpu. The PWM area sink has plenty of clearance.
PWM sink clearance
Finished mount with Crossfire bridge poking through. I did need to spread the fins to get the bridge through. (photo is old one with old gooey pads on sink, but main focus here is to show dimensions of sink.) Thickness is nearly the same as any double slotted HSF, and height of 1+7/8 inches from the edge of the card. About 3/4" to 1" from the side door of my Antec 900. Length shorter than card.
Mounted S1
Finally installed on Abit IP-35 Pro. An additional S1 Rev. 2 will arrive today to finish the job, along with a new P5Q-E!
Installed
Edit: I installed my Rev. 2 and happy to report a similar installation as Rev. 1.
There is no right or wrong here but remember to pay attention to which way you have your ram heatsinks mounted as you want them to receive as much airflow as possible.Quote:

I encountered same troubles with RAM sink, just cut it with dremel. AC S1 is a... cheap heatsink, you'll have to adjust things so that they fit well. I did the same for PWM heatsink but I couldn't use the standart thermal tape and use arctic cermic but it doesn't touch the PWM chip well... I need to find where to buy this kind of thermal pad such as those you get with the stock heatsink...
USing a duo orb on m 4850 , dont know what temps were like with stock cooler never tried it after reading they were high. Mine idles at around 36 and under load is abotu 49 degrees
Why is everybody posting pictures of there "awesome" aftermarket coolers with gpu-z under a 0-2% load?
That tells us nothing, thats just idle temps in 2d (xp) or low 3d (vista aero) mode. Go download ATI Tool and run the artifact tester, this will push the gpu in to 3dmode and 98-100% load, this is a great test of both your stability of an overclock and your load temps.
Most people are suffering high temps with the stock coolers due to the awful stock fan speeds. It maxes out at like 22% under load. I suppose the idea could have been two fold.
1.) Keep the noise down to near silent
or
2.) Keep the temps high to limit overclocking
Ether way since you can manually override fan speed via the profiles xml file boosting my 4850's fan speed to 30% dropped idle to under 50, and load to like 70's. For more graphic intensive games like crysis I created a 2nd profile that has the gpu overclocked to 675/1050 and boost the fan speed to 60% and I turn it on before gaming, the cards become abit loud but I do not hear them in the game and they stay nice and cool. At this point it would be much cheaper and better to just get some 120mm fans to point at the voltage regulators to drop those temps as they are sort of hot and keep the stock coolers.
It looks like many of you are not getting better performance with these after market coolers its just that you have not taken the time to increase the broken fan speed on the stock solutions. There are some MUCH better coolers than stock, but they cost too much to warrent in my book. (got the cards for 150$ each on sale, id be damned to pay 40-70$ for a cooler when the cards run fine with the stock coolers, only in the event of heavy volt moding would it be worth it)
Keep in mind my temps are high even because I have a P182 SE case, one intake for the upper chamber and its blocked by a dust filter & the dust filter door & the case door. If I open the doors and remove the filter I drop 5c idle and 10c load instantly.
im sure that ATI will release a better driver soon to fix this problem with the fan speed. bug them enough and they get around to doing things :P

already posted in the 4800 thread but it fits good in this one also.

ambient temp 25\26º and did not pass 48\49º so far :)
very happy now with good temps and no noise at all with this fan speed.
:up:
Wow those are great temps, esp for the voltage regulators. Now overclock it already! (and try the artifact tester instead of the 3dview)
damn....some good results there :D and that cooler I can find where i stay :D
How much bigger is that cooler compared to the stock one jpcastro??
Im still wondering if i should buy a after market cooler or just wait for better drivers
yes there is a "problem" with the voltage\power zone the vf1000 dosen´t bring any additional ramsink like the HR03 gt for example.Quote:

for me low noise and good temps are essential so is always a good investement, with stockcooler even with the fan at 35\40% the card achives 80º and that´s to much for rest of the PC.
and the results were made with the fan in silent mode, gonna make more tests with games and scan for artifacts with the fan at more higher speeds.
