I have been building my watercooling kit for a long time now (mainly because of limited budget), self-made blocks (#Rotor -style CPU, NB & GPU) etc and I bought an used Hydor L30 to go with it. Now that I have been doing my final leak test and such I discovered that the pump is surprisingly noisy and gets too hot for my liking (well, it might have something to do with me replacing the barbs with better flowing ones, but I somehow doubt it)... So here goes
pretty much the whole system (I have since changed the GPU top plate to copper one since all tries at polycarb top leaked)
The pump at its current state
and finally an extremely blurry pic of the GPU block with the new top being leaktested
the pump measured 42.1 degrees C (on top which felt hottest), the water (measured through the hose) 40.0C and the block 42.6C...

those figures are way too high to my liking, what do you think? Is it normal for L30 to get so hot?
...sorry for this newbieshly post but I feel the need of reassurance right now
