HD4850 is definitely not a HOT Card (temp wise)

I know this has been stated by many people throughout different threads but I just wanted to clarify that the HD4850 contrary to popular belief is actually a pretty cool card. If you were lucky enough to buy the ASUS version you get Asus SmartDoctor with it and if u merely put the fan on 60% (slight buzz) you get temps idleing mid to high 40s and under full load low 60s. I have my card in overdive at 700MHZ and memory at 1110MHZ and at full usage it goes up to the high 60s. This is MUCH cooler than my old 8800GT. For those of you that dont have Asus, just be patient your card will be cooled down soon(when they fix the fan options). The card works great and I dont like hearing that people aren't buying because it supposedly runs superhot. So if ur looking to buy the 4850 and don't want to wait, Grab the Asus for now, its good stuff.

I have a vision tech 4870 comming from tiger direct on july 9th and I will try that or mabey by then riva tuner will be okay for fan control ?

I have heard that smart doctor works only for ASUS and that rivatuner isn't updated for the 4800s yet...however it probably will be soon...as for overdrive, after more testing, its still a bit unstable even tho it got a passing rating when overdrive tested it. I'm hoping new drivers will fix this problem...overall- badass card

There's an easy fix thru Catalyst Control Centre and you don't necessarily need those programmes to up the fan speed...google 4850 fan speed fix and you'll see several links to do it thru CCC...it is easy and works a treat...I had difficulty finding the file but that's cause I was looking in the wrong place but once I found it was a breeze...and my fan temps that were around 60 on idle are now around 42....piece of cake.

superman099 tell us a little more about the computer setup, case, fans ect...
How good is your case airflow.

Could help compare against other system setups that are hot.

my 4870 is at 45 C idle with fan speed at 40%.

Got a HIS HD4850 ICEQ4 Turbo, idles @ 51C - 12% Fan. default speed is 650MHz so only +25MHz over stock speed. It's a dual slot cooler plus the memory and GPU have separate heatsinks, so hopefully the RAM doesn't get cooked.

yet to find out load temp and associated fan speed.

My 4870 is at 43c at fan 30% overdrived to 765/1000 and load never goes over 65c. using cat 8.10

Got a Gigabyte GV-R485MC-1GH.

A Radeon HD4850 card with PASSIVE cooling and 1 Gig of memory.

Idle max 55'C.
Stressed max 95'C!

(had a 8800GTS with fan (very audible) before. Temps were 45 and 75)

Airflow in the Chieftec bigtower is optimzed. Casefans are at halfspeed.

Seems to be okay at these temps.

My two cents: if it works without a fan, then it should be even better with one.

Haven't done any overclocking though.

ive been using a Palit HD4850 Sonic for sometime and its Idle temp has never gone above 44c.
on load it s always below 80c(mostly in early 70's).

I have the MSI 4850 OC 512mb that meadowla shows in pics above. I idle at 36°C and I haven't seen it go above 42°C under load yet. Of course, it's winter but I don't think the temps will change that much in summer.
