Hello.

are these sufficient for following specs ;

I5-4670K 4.5 @ 1.28v (delid), wont overclock higher

XFX R9 290 ( currently on air, will add block later )

W.cooling ; Alphacool NexXxoS ST30 Full Copper 120mm
Unbranded 240mm copper(?) rad (30mm)
EK-Supreme LTX CSQ 1155 block
EK-Reservoir Combo DCP 2.2 (pump+res)
and ofcourse tubing & fittings.

Will use 2x 1850Gt's on the 240mm and possibly 1-2x cougars on the 120mm (or vice versa)

Case is Fractal define R4

The 240mm radiator is fine for the cpu but you should really add another 120mm radiator for the GPU. The rule of thumb that i always like to follow is 240mm for a cpu or 360 if you pushing the extreme OC, then add 120mm for every extra component added to the loop.


Since it is a custom loop you can give it a try with only a 240mm and if your not happy you can add a 120mm to the back of the case in between the cpu and gpu.

Hi chromic, I'm curios when you say "I5-4670K 4.5 @ 1.28v (delid), wont overclock higher"?

Do you mean you yourself won't take it any higher than 4.5ghz? or your present air cooling won't allow going any higher than 4.5ghz, and that's why you're considering water cooling?

It seems that if you delidded the CPU you were definitely at some point after a higher CPU clock than you were getting?

I don't know the air cooler you are presently using but I would guess it is the higher end of air coolers and if it is the setup you are considering above may seriously disappoint you with the cooling performance it yields vs a high quality heat pipe air cooler?

One of the most common major mistakes made in a first step to water cooling is not enough radiator cooling field to do the job, many try to fit it all inside of a case and the end result in the water cooling performance is barely competitive with the cheaper air cooler.

Why don't you read this and see if your considerations and questions change, I want to help you, but I also want your end cooling performance satisfaction to be what you're after.

4670K is currently cooled by Antec h2o 1250 240mm AIO cooler - 70c on prime95 smallfft.

4.7ghz needs more than 1.36v, and i dont like voltages that high, and 4.5 is enough for my needs. :) (mostly gaming)

Changed for custom WC, cause i got it very cheap. :D

If that's the case why do you want to spend the extra money for a custom loop that's probably not going to give you much better cooling performance at all, than you already have?

Edit: My Bad, Missed the very cheap statement!

So if you've already bought what you listed what do you need to know?

Cause i really got it CHEAP. :D

And i dont really like my reference 290 sound nor 90c temp..

edit : I still need coolant, and im not sure where to position the rads (1250 mounted on top & it resonates like a mofo.

And my main question was, that would the 240 & 120mm be enough for both the CPU & GPU (would OC the gpu)

btw, do i need a backplate etc for the cpu block? & FYI, this is my 1st custom loop. :)

When you say enough?

Enough for what?

Could it actually run?

Of course it could, but your deltaT with an overclocked 4670K CPU and overclocked R9 290, get ready for some deltaT shock therapy, IMO you will be seriously short on radiator cooling field.

Is it the EK pump combo you have listed in your first post?

W.cooling ; Alphacool NexXxoS ST30 Full Copper 120mm
Unbranded 240mm copper(?) rad (30mm)
EK-Supreme LTX CSQ 1155 block
EK-Reservoir Combo DCP 2.2 (pump+res)
and ofcourse tubing & fittings.

Also, what is the 'unbranded' radiator? Do you have a link to it?
