ATI 4850 TEMPERATURE discussion

[kpxgq]

i have a concern with the XML-fix

since you are changing the FAN-ALGORITHM-SPEED setting to MANUAL, and forcing it to 35 or whatever, does that mean that the fan is at 35 all the time? because I feel 35 is quiet and sufficient for idle/2d use but probably not enough for 3d games. before, when the FAN-ALGORITHM-SPEED setting was at AUTOMATIC, it would change the fan speed on the fly, correct? In that case, would it be better to leave the FAN-ALGORITHM-SPEED setting to AUTO but just upping the speed #?

anyone get what im saying?

I get what you are saying. What some people do is set 2 profiles. For example, create one profile for "fan 35%" and another one for "fan 60%", then edit their respective xml files. Then you can switch back and forth between the profiles.

And yes, if you left in automatic, then the fan does rev up eventually, but not until your card is cooking at like 90C, and this makes people uncomfortable.

 

[unr3al]

When I buy my HD48x0 (still have to see which one I will eventually get) I'll simply get a ThermalRight HR-03 GT and stick a 92mm fan on. Should solve the temp problem, methinks...

Warranty? Bah I overclock every component I can overclock once I have confirmed that they are in working order rofl so warranty void within the first two weeks after purchase...

 

[proxopspete]

I have Duorb on it... no mods necessary...

Room temp is 80F (27C)

Idle temp is at 52C and load temp (running GPU Folding@Home) is 62C.

 

[chizow]

Here's some cheap options that might help some of you folks looking for improved cooling:

Antec Cooling at MicroCenter

Cyclone Blower for $1.99 and Spot Fan for $9.99. I don't know how much their shipping is, or if it kills the deal, but if you have a B&M near you and want to cool down your cards these should help for sure for a nice price.

So, take them up on their promise of satisfaction, and if it bricks during bios flash, replace it.
AMD is at fault to begin with, the manufacturer is at fault for not fixing it in bios, and the seller is at fault for selling you such a product.
The customer is the only one who is NOT at fault here.

I don't think I have seen the links, so here they are:

4850 bios from MSI (works on HIS and VisionTek too, should work on all of them) with the powerplay fixed (it will correctly lower core clock from 625 to 150mhz when idle):
http://www.techpowerup.com/vga...HD4850.512.080605.html

Windows update tool:
http://www.techpowerup.com/downloads/1122/mirrors.php
Run the tool, select the bios file, click program, windows WILL COMPLETELY FREEZE! nothing will move, even caps lock will not work! this will go on for about a minute, don't touch anything and wait. After a minute things will start moving again and a message "bios was flashed successfully" will pop up, asking you to restart, click yes.

Note: yea i didn't care much when I thought it was just a fanspeed adjustment, but it turns out this actually underclocks the card properly when in 2d. This means less power consumption, thus, lower monthly power bill.

 

[ApBp]

Can anyone recommend a VGA cooler from these three? With the profile workaround at 40%, temps are great while it is idle, but when it is at load it still reaches 85c+ (in Grid Demo and CoD4) and I dont want to raise the fan anymore since then I start hearing it. Plus I need a cooler anyways since I'll be OC'ing it later on when the right tools comes out.

Thermaltake CL-G0102 VGA Cooler

ZALMAN VF900 ? CU 2 Ball VGA Cooler

ARCTIC COOLING ACCELS1 Rev 2 VGA Cooler
http://www.newegg.com/Product/...x?Item=N82E16835186016

I know from reading this thread that the accelS1 is really good, but havent really heard anything about the first two. Also, I am able to pick up the first two at Fry's right away while with the Accels1, i'll need to order online. At the moment, i'm leaning towards the accel, but if the first two also does a decent job, then i can pick those up right away. Oh, and noise level is pretty important too.

80c idle defective? lol... sounds more like user... but oh well...

even if it is 80c... does it still function properly? Even it it was 500C, as long as the card boots and does what video cards do then the man. has done what it should.

 

[Twigger]

I've been playing around with the XML file. It seems if you set the RPM% target to your desired percentage (I chose 35%) and set the mode to Automatic, it still works fine and allows the fan to spool up higher than 35% when at full load. The profile didn't require reloading every time Windows [XP] started, either.

However, since I always prefer hardware (not software) fixes to hardware issues, I downloaded TechPowerUp's Radeon BIOS Editor v. 1.11 and easily edited my fan speed profile. It's working like a charm, and I don't have to worry about CCC and the profile loading correctly.

At 35% idle, my GPU is sitting at 47C with a 26C room temperature and decent case ventilation. (My comp. is set up for near-silent operation.)

cards don't fuction properly at 80c. They function TEMPORARILY at 80c. Most people are getting 80c, and the cards are acting up, even it works right, it will die within a few months.

ApBp:
Consider running 50% or something, with mine set at 45% I can run F@H GPU client (fully loads video card) and the card only hits 58C max. Of course, right now it's just sitting open on my desk mounted on a bare motherboard, so airflow is better than in a case. Make sure you've got adequate ventilation in your case and you should be fine.

Taltamir:
Which model 4850 do you have (MSI, VT, etc)? I hate flashing BIOSs, always makes me nervous that I'm going to brick the card or something. I wonder if VT will release a similar fix?

 

[taltamir]

I have a VT, i flashed it with the MSI bios... so now it idles at 78c instead of 82c...
I hope at least the power consumption is lower (since it actually underclocks).

Anyways, with such horrible temps. I probably will return it to frys in a week or two (if it doesn't die before) and buy a 4870x2 when it is out.

Yea, after some temp tests with Real Time HDR IBL, I just decided to set two profiles like suggested earlier. 40% for desktop and 65% for gaming. Though the fan is loud it kept my temps in the 74-75c range. Not perfect but will do for now.

But I would still like suggestions on my previous posts about the three vga coolers.

Hey guys, check this out: new Arctic Cooling heatsink, with 4850/4870 compatibility. It looks like it'll be selling for around $34.95, so little more expensive than the Accelero S1 Rev 2, but much cheaper than a HR-03.

A Thermalright fan is now impressed...

That would be a shame. With some simple BIOS tweaks, you can easily take control of your temps with the reference 4850 cooler. Try TechPowerUp's Radeon BIOS Editor. It's very easy to use, especially if you're already comfortable flashing your card's BIOS. My card now idles at 47-48 degC.

Damn. Will probably just wait for that instead of jumping on the Accelero S1 bandwagon now lol.

That apparatus should cool very well, but the beauty of the S1 is no need to have any fans (or worry about them failing) and run a fully cranked 4850 at less than 65C in 82F ambient.

I no longer even need to monitor my gpu temps, simply a moot point.

But I wouldn't be running the S1 without a fan lol. I was going to buy a separate 140mm fan o strap to it. But the Twin Turbo saves me space, and having to buy a separate fan. basically a more compact solution.

More compact, not necessarily cooler.

It says in that article that it optimises airflow to 40cfm, whereas the 140mm fan I have strapped to the S1 'optimises' airflow to 109.6cfm, and is barely audible.

So i think the 140mm way of going is probably cooler, but is less space efficient. This product will be the best solution for those wanting both space saving and good cooling qualities.

Exactly. A very nice luxury to have.

Thanks for the link, it came in handy.
I think I will have to reapply the thermal paste for temps like yours (or REALLY rev up the fan to annoying levels)..

With a fixed underclocking bios that has been modified with the "suggested fan auto speed profile" built into the that utility i went down from 78c idle / 84c @ 50% (47% utilization during coh according to catalyst) to 52c idle / 70c @ 50% / 80c load

Still not as good as I would like, but meh. Turns out city of heroes was crashing the video card because of the beta driver i installed, not because of the temperatures.

I have still not come to a decision, I would really like to buy one that comes with a decent fan to begin with... and with a non broken bios...

Here's the thing though, I also have a fan bracket and a 140mm fan facing the side of my PC blowing in, directly over the GPU and much of the mobo. With the Accelero S1, I have to remove that side fan, because it won't fit. I think with the TWIn TURBo I'll have just enough space, but will cut it very thin.

Accelero Twin Turbo.

212 L x 103 W x 34 H mm

Accelero S1 rev.2.

215 L x 138 W x 33 H mm

The TT is nearly 4cm less wide. Which is a god send for me.

 

[User5]

very nice fix indeed. My temps went from 80c to 50c, IDLE. And I only increased the 23 value to 40. Any louder I can hear it, but is it okay to be running the fan so much faster than the value they put it at? Why exactly did they even do this in the first place??!
