I using Cooltrek Vostok water cooling kit, bought 1 year ago by RM480....perfomance quite good, but the pump is suck, leaking water...fix it more than 4-5 times, finally i decided to dissembling the pump to took the rubber seal out and "custom" sealed by using "elephant super glue"(RM2) , now no leaking problem after half year used...but can't open the pump again forever....

No, water not leak from the tube, but leak from the gap between the glass base and aluminium casing of the pump...

NOT between the Barbs and the pump la bro....

Oh ya...what a good solution ....unfortunately i fixed it long time ago....

Of course la, ur NB contribute a lot of heat....
