ATI 4850 TEMPERATURE discussion

[brandonb]

With the XML fix, you don't have to make a custom profile, you can just edit the "profile.xml" that already exists, and reboot. It will apply to the computer as its the default profile so you don't have to activate anything. However, I suggest only doing this after changing all your other settings. As going in and monkeying with things will probably reset it.

Is there anyway to fit an Accelero S1 without having to do hacksaw mods? I just want something that will improve temps, but is easy as anything to put on.

 

[chewietobbacca]

i don't think you need to mod it to fit the Accelero S1... if it works on a 3800 itll work on the 4800's since they have the same mounting holes

 

[nib95]

Hmm...decisions decisions. I can either buy the Asus 4870 for £220, or the Gigabyte one for £200, and spend an extra £22 on an Accelero S1, a 140mm fan and some thermal tape. I've never fit a GPU cooler on, and am a bit anxious. My only fear is that I'll mess up, and that I'll end up finding out that custom fan levels (40% etc) on the stock cooler will end up dropping temps enough for me to not bother needing the Accelero S1.

What do you guys think? Are these things hard to fit for a complete n00b? Stick with default or go with modded cooling?

Why all this talk about aftermarket fans still? Just edit the profile.xml file and your done! No worries about voiding warranty and its free!

Because some of us are still not comfortable with idle temps of 50c. Plus, I want a quiet PC, not something that sounds like it's about to take off.

The stock fan will likely do for most people's needs, but it is a piece of shit. It isn't copper, it's aluminium painted in copper paint. No wonder it got hot.

For just a few bucks extra and a bit of time, I'd much rather know that the card is cool, even when I clock it to 700Mhz.


Just my $0.02.

Well I got into the file (thanks for the help!) and this is all that's in there for me. I have the MSI card and am using the drivers and CCC off of the driver CD.

I don't see the profile file that is mentioned earlier in this thread, page 7. You may need newer drivers? Editing those was very easy! Good luck

Source? What I saw when I took off the cooler, namely this.

You can clearly see the grey coloured surfaces around where the holes are, the copper colour appears to be a copper 'layer', albeit a very thin one. You can also scratch off the paint to reveal the grey surface.

Which kinda begs the question, why paint something in a copper coloured paint if it's made of copper?

It still doesn't really matter, aluminium heatsinks also do the job. And I certainly aint bashing ATI, I love 'em.

I just believe their heatsink is by design, fully intentional so that most can't unlock the core's potential. Because with a slight volt mod, this should easily go over 750Mhz, given that it's the same chip as the 4870.

And I'm sure almost all of the chips on the market will be fine with the stock cooler.


Me, I wanna overclock it to +800Mhz. It can't fry if it has 4870 voltage going through it, it's the same chip. It also can't fry if it's loading at 41c, which it is now @ 700Mhz stable. These 4850 chips have a lot of potential.

 

[Rhino2]

Ah ok, thanks, I wasn't trying to seem like I was attacking you or anything, was just curious

 

[Delerious]

This thread has been very useful. As for my situation -- Yes cost is a factor. $162 after tax for the card is nice and I didn't really want to pay anymore, but after putting a Zalman VF900 on it for $25 from eBay -- I can clock it to the max and keep the temp cool.. It definitely seems worth it to get an aftermarket cooling solution.

i added an accelero s1 r2 to my 4850 yesterday. took about an hour start-to-finish since i let the card and its ramsinks bake in the florida sun for 30 minutes. (that ramsinks were firmly in place afterwards.) i followed muckey's technique and used a hacksaw blade to shave off the existing heatsink to cover the VR area. (the heatsink is aluminum painted to look like cooper so it only takes about 3 minutes to cut through it.) since i've got an 80mm fan hanging on the accelero, i probably could have put the ramsinks on the VRs and let the fan cool the memory. then no hacksaw would have been necessary and the original cooler could have been reinstalled in the future.

my temps are a bit warm but acceptable for me. 690mhz core/1125mhz ram, 43c idle/63c load.

Copper painted aluminum? Source?

I'll verify. The core is a very small piece of copper and the array of thin fins above it are copper that are soldered to aluminum. The remainder of it is copper colored painted aluminum. I am not at all impressed with the quality of the sink.

I like the fact of using a stationary piece of equipment (S1) as opposed to a fan that has the potential to fail.

I am comfortable with modding and have never had a cpu or video card failure in 15+ years of using.

The risk is well worth it for my situation, besides, S1lence is golden

What's this about hacksaw? I don;t want to get it if it will require any modding beyond the fitting. Can someone confirm or deny whether I'll need to do any hacksawing fitting the Accelero S1 to a 4870?

 

[ApBp]

I think the only thing they sawed off was something from the stock cooler to cover the VR area. Its entirely optional I believe. Also, if you have some ramsinks, you can probably use those to cover it as well, no sawing needed. But i'm not too entirely sure.

That is correct.

This is correct, ram sinks will work great, no need for sawing. I didn't have any spares and didn't care to wait....

@ Rhino2

No, didn't think you were attacking me at all.

You asked a question almost everybody asks when somebody makes a claim or statement, and a very reasonable one, to prove a source of information. Was happy to provide an answer. And regardless of whether that heatsink is copper or aluminium, it still cools the chip. Obviously the problem with 4850s was to do with how fan speeds are set, but I do agree with Mucker when he reckons the quality of the cooler's not up to snuff.

And he might agree with me that this was a deliberate move on the part of the manufacturer, to retain more of a gap between this card and the 4870. Somebody else first mentioned that on here, can't remember who, think it was Steelsix, that ATI had neutered the card because otherwise it had the potential to become a bit too good.

This is correct. And I've seen future versions of these cards that don't even bother with ramsinks or voltage regulator cooling, but these cards are actively cooled with a good cooler. I used ramsinks on mine though.


Edited for various appallingly bad mistakes.

Look here.

Again, it's only a few bucks for the heatsink, and a few more for some ramsinks. I just bought a couple of the Zalman blue packs and did the lot with it. I have never been so impressed with a cooler as the S1, truly outstanding performance. I actually have a fan on mine, a 140mm one. Nice to know that if the fan fails, the card will still run games and not burn up.


Plus, if ever I need to send it back, I can remount the factory heatsink. I doubt they'd notice because as somebody else here said, if you make as crap a job of it as they did, they're never gonna find out.

 

[Mucker]

Actually if they really took a good look at the TIM, they could easily determine the type used and void your warranty. Probably a good idea to keep some of that old TIM around for RMA time

 

[Modular]

Whew! Finally got it. I had to reinstall CCC and all the drivers using the Hotfix drivers from ATI instead of the MSI ones on the CD. Thanks for the help!

for 3870/3850 you could use RivaTurner to speed the fan to 50%... anything above 60% = a bit noisy.

for 4850 you could wait for RivaTurner 2.10 or if you have an ASUS 4850 you could use program such as Smart Doctor

nVidia doesn't have this problem because the "nVidia system tools" can automatically change the fan speed.

I have the ASUS 4850 but only installed the Catalyst base drivers because I don't want all that CCC crap. BUt once I discovered the heat issues I installed CCC and SmartDoctor and yet it still wants me to install GamerOSD! wtf. Anybody know what this garbage is? Does it put a bunch of crap in my services and startup? Gah, I hate that!

 

[nib95]

Can someone give me sizes on the 4870 and 8800 GTS 512mb?

I'm trying to figure out whether I have space for the 4870 + Accelero + a 140mm fan attached to it.

Below my 8800 GTS I currently have about an inch+ space before the next component. I think that should be enough for the accelero and a fan strapped to it. However, from the edge of my GPU, to my side case fan, I have but a few mm, maybe a centimetre or two. Is the 4870/accelero much wider than the 8800 GTS?
