Upgrading setup advice needed

[fenchu]

I was hoping for some advice on upgrading my setup below is my current setup with the cpu + block i want to add , im hoping
adding the cpu will not raise temps to much at the moment i peak @ 47c using heaven bench or witcher 3 for a
extended period of time if gpu is at close to 100%. Im hoping im can cpu block and not affect temps to much ....

EK - XRES 140 D5 vario

Black ice GT Stealth 240 mm Radiator
2x ek vardar fans f4 pull
2x Aerocool DS Edition fans Push

XSPC EX420 Triple Fan Radiator
3x Phanteks PH-F140SP 140mm Fan push

EK Water Blocks EK-FC Titan X - Acetal+Nickel & backplate

current setup :-

res > pump > 240 rad > gpu > 420 rad > res

I want to add to this setup and im hoping it will not affect temps to much, i was thinking

res > pump > 240 rad > gpu > cpu > 420 rad > res

the block i wanted to use was this one :-

Yep, you have enough rad space to upgrade with a cpu block !
