Sickleflow 120 whining noise

[clw0315]

About a month ago I installed sicleflow 120's onto my h100i as replacements for the fans that came with h100i which were very loud. The sickelflows unfortunately have been making a very annoying whining noise sometimes. This noise is heard almost without stop when the computer boots or comes out of sleep mode and is heard for several minutes after the computer has fully booted. It is connected to the h100i not directly to the motherboard and it also seems as if they stop whining when the CPU gets hotter (running prime95 almost instantly stops the noise and it doesn't start again until the cpu temp goes back down). I know this is very weird but is there anyway to stop this extremely annoying noise?

It might be a good idea to keep the fan speed up in the Corsair settings thing. The sickleflow are sleeve bearings so they won't hold up well when mounted horizontally.
