Ah, thanks for the calculations! I got around the same figures based on a WC theory thread I read on Tom's Hardware. Just to confirm:
Heat Generation calculation:
i5-4690k TDP: 88W
i5-4690k Overclock: 88W x 1.35 = 120WSource
120W of heat generation means 1 x 120mm/140mm can remove heat, with average rate flow, good static pressure and good radiator.Source
Idle Power: 36 (normal), 40 (overclocked)
Load Power: 99 (normal), 126 (overclocked)
Extremes: 150 (normal), 200 (overclocked)Source4690k Power Consumption Link
Upper Max 150W thermal generation
Heat Dissipation Calculation:
(LxWxH) x 0.00023129193 = Watts dissipated for 10°C delta-T (estimated)
Using 92mm x 92mm x 54mm, 105W.SourceTL;DR
A 92mm fan will have trouble dissipating heat during long-period load power draws, possibly having a delta-T greater than 15°C.@Laine
, I thoroughly respect your work so I'm going to ask you, since you worked around the same case. Do you recommend a temperature sensor for the loop? I read some threads regarding higher water temps frying DDC pumps.

Haha, actually I have small stock of other fittings I bought from last time. I did some quick math and it all added up to around 450 USD, so I'm not as far as it appears.
