I am thinking of this kit with an extra rad assembly and mc50 and mc20 gpu and N.B. blocks. Space is an issue with my case, also I dont have enough flow in the front due to the case designto use a 120mm in front. It is an X-Dreamer case so I will be using the two rads in the back. Is this a good enough setup? Is it better than the cooling I have now? I am 49 celsius at load. Thanks.
