Reputation: 62 ![]() Rep Power: 2 | ...I originated none of this, but: Control Fan Speed of YOUR NEW Radeon 4850/4870 - Graphic Hardware - Forums - www.atomicmpc.com.au Since I just built 6 rigs for a gaming center, and noticed that the 4850s run effing HOT, I gave it a try. Under normal settings, the fan is nearly silent - but idle temp was 77C! I bumped it to 50%, and the fan is clearly audible but not bad (for a gaming rig), and the idle temp dropped to 53C in less than a minute and I stopped watching. |

After a couple minutes it dropped to 51C. I am sure that someone is going to come out with an aftermarket cooler for these things - but really, just running the existing fan faster makes a massive difference. To be honest, I would not be comfortable at all running them at stock settings. That's just asinine...77C! | |

While that is valid, it also would have helped if they didn't try for a single-slot cooler on the 4850s. And/or opted for more air movement. The fan on them now (I got Sapphire models) is dead quiet at stock settings, but is noticeable at 50% - probably obnoxious at 75%. I see no reason why they couldn't put a better fan on the single-slot cooler to move more air without causing too much noise. Other than cost, I would reckon. I'm happy with the value the 4850 brings to the table...just wish I didn't have to edit XML files to get them to operate at reasonable temperatures. | |

Reputation: 98 ![]() Rep Power: 2 | The stock fan on the first series of 8800GTs was also silent on auto (which would stick to 29% then jump to a very high speed when temps got beyond a certian point). Without ventilation openings of the underlying expansion slots it easily idled at a blistering 71c! Now I've got absolute silence with fanspeed down halfway and I'm idling 41c on a hot day with a good <39 scaling as ambient temps drop. (It's 39c right now) Oh by the way. You really should try the thermalright hr-03-gt on the 4870. It will definitely keep the load temp in the 50s and with a good fan even lower. I've heard wonderful things about this cooler.
