The Cheetahs leapfrogged Sharks to go top of the Currie Cup table, consigning their opponents to a 38-30 defeat at Kings Park on Saturday.
Cheetahs ran in five tries to the hosts' two in Durban to maintain their 100 per cent record after five games and replace Sharks at the summit.
A penalty try and a Michael van der Spuy score as well as seven points from the boot of fly-half Fred Zeilinga gave Cheetahs a 17-12 lead at half-time.
Tian Meyer chased his own kick to add a third try for Cheetahs, with Uzair Cassiem and Shaun Venter also touching down to ensure tries from Francois Kleinhans and Thomas du Toit, as well as teenage full-back Curwin Bosch's 20-point haul, were in vain for Sharks.
Blue Bulls are up to third after Jamba Ulengo scored two of their six tries in a 41-14 demolition of Pumas at the Mbombela Stadium.
Ulrich Beyers, Travis Ismaiel and Nic de Jager dotted down in the first half, while Hanro Liebenberg - captaining his side for the first time - also went over before Ulengo helped himself to a double.
