MSI Afterburner

[Peter450]

I used this to clock my 4870 to 650/1300/1700

I used the stock fan profile, i noticed though that the fan kicks in really hard and loud sometimes, i checked the temps and they were like 90C which seems pretty hot, i think the fan runs normally at a very low level and then comes in really loud when the card gets hot

If i turn the fan control to manual, i can set a much higher fan speed, for normal operation, and this should keep the card running cooler, so i dont get this fan on fan off of the auto setup

My old GTX 280 was also OC and i had the fan on 75%, this kept the card cool and was not to noisy

The OC on my 4870 is quite conservative so would 65% on the fan on manual be enough to keep it cool?

Also if the card does hot up, will the fan speed go up in manual mode or it stay set at whatever % you put in regardless of how hot the card gets?

I'd like to set it at a level, that keeps it cool, and is not to noisy, the auto setup as per above seems to either be off or very low and then kicks in with an almight bang which is quite annoying really

@OP

HD4870 does not have a shader...its linked to the core(basicly whatever the core is clock at)


also why did you go from a GTX280 to a HD4870 i don't get it?

you can set a custom profile with afterbuner as I done so with my GTX480.

All the numbers a wrong, stock clocks of a 4870 are 750Mhz core and 900Mhz RAM

Just a typo it would seem.

Now correct your post to 470.
