so 68C under pressure is OK?

I touch the GPU's fan and it stops, I touch the CPU's and my finger goes 'Zzzzzzzzzzzz' against the fan, I plugged another fan I bought (using an adapter) on the same 4-pin cables the DVD/HDD etc. get power from and it wasnt strong enough, I then plugged it into the mobo and it was very strong, the same I guess applies with the GPU's fan; it isn't strong enough because its plugged into the 4-pin power cable. What do you think I can do?
