Radeon HD 4890
The Radeon HD 4890 is a Radeon HD 4870 with higher clocks, an alteration rendered possilble through a new revision of the GPU optimised for this: the RV790. The stock cooling system is similar but slightly sturdier.

The Radeon HD 4890 is better cooled than the Radeon HD 4870, AMD having improved calibration of the cooling system.
Temperature and noise level readings
Although the GPU is better cooled, this comes at the price of higher sound levels. The influence on the rest of the system is similar overall to what we noted for the Radeon HD 4870, that is to say that heat from the card also causes other system components to heat up.
