Tnx for your repley Cesthree and leeghoofd..

This is my WC

TFC Xchanger Quad
Swiftech apogee XT
EK-Multioption Reservoir 250 rev.2
Koolance Pump PMP-450s
EK-D5 X-TOP G1/4 Rev.2
4X TFC Triebwerk TK-122 - 1800RPM - 120MMx55MM
Tygon R3603 - HighFlow - 3/8 ID - 5/8 OD - Clear
Feser One Cooling Fluid - UV CLEAR / BLUE
10MM (3/8 ID - 5/8 OD) Feser Schroeffitting - G1/4

Sorry for not beeing clear in my question.. I ran a quick LinX 1024 on 4.2 clock just before i installed my WC.. just to compare the temps Air vs WC.. Not to bench or 24/7
I wanted to know if the 30 degree improvement is acceptable ?
