Chiefs coach Dave Rennie feels his side coped better with the energy-sapping conditions in Saturday's win over the Stormers at sunny Newlands.
Once the Chiefs turned on the heat, the Stormers found themselves out in the cold and their impressive four-match winning streak came to an end with a 28-19 defeat in front of their home fans.
"The Stormers looked like they were tiring towards the end of the match," said Rennie.
"We're a very fit side and it looked like we were coping well.
"We controlled the ball more and it's difficult when you're made to chase (the ball)."
The Chiefs run-on XV showed five changes to their side last weekend and the intention was to play with spark and pace. The ploy worked like a charm as the Stormers looked jaded in the later stages of the match.
"We tried to move them around a bit and it worked," added Rennie.
"It was ironic that last week we dominated the scrums and we lost; this time our scrums were not good and we end up winning. The scrum is one area that we need to improve on."
