Question Will my liquid cooler be damaged if the tubes touch the GPU heatsink

[Toreth]

After reading some information saying it's best to mount the liquid cooler radiator with the tubes at the bottom instead of the tubes at the top, I remounted my radiator to put the tubes at the bottom. However, the tubes are stretched to their limit and they touch the edge of the GPU heatsink. Is that OK, or will that cause damage to the tubes or the cooler?

Shouldn't be an issue IMO.
