Do you think it would be undersized? This h140-x performs just like a corsair h110i for the cpu.
Thanks in advance!
Just forgot to mention some important things:Fans
: best upgrade for money is getting some new fans. Now, I don't know the specific fans that comes with the h140-x but I guess they aren't better than any of the other AIO watercooling sets I've tried.
This Means they are unncessarily loud and underperforms compared to some good aftermarket fans: The best 120mm fan I have ever used for watercooling is Noctua NF-F12 PWN
. The keyword for a good fan for radiators is static pressure
. Anyone who embarge on the watercooling hobby must learn this term.
One of these fans worked better in push than the fans that came with the Corsair H80i
in push/pull! No kidding. And way more quiet at the same time. I have a single of these fans running just pull, so I seriously can't hear it at all (and I'm notoriously noise sensitive), unless I have gamed for a while and the system gets very hot.Pump flowrate:
This is also a term any new wannabe watercooler needs to know. At least if they plan on overclocking. When overclocking the CPU gets really hot really fast. The key to keeping it cool is to rapidly change the water in the CPU-block. If you have a high flow rate, the water gets rapidly changed from warm to cold.
Of course with a high flowrate the water stays in the radiator for less time, and thus have less of a chance to get cooled down. This Means the radiator must be effective. The easy way to make a radiator effectie is to add fans, or upgrade fans (see my note on Noctua above).
Another option is to get an upgraded radiator. Normally this is with higher fincount pr inch (fpi - new term). This in turn require a fan with high static pressure
, or the air will get deflected to the sides (remember the Noctua).
Another way to optimize a radiator for heat-exchangeing is to add more pipes to the radiator. You can call it single, double or some other term, but it boils (pun intended) down to the water staying in the radiator for a longer time.
This last thing really tends to kill the flowrate though!!Pump head
This leads to yet another very important term in watercooling terminology (sp?). In short it defines the pump's abiliy to keep up the flowrate when various flow-restricting items are introduced to the loop. These items might be an extra waterblock. Flow-Measurement equipment. Bends and kinks in the tubing (very minor obstacle). Long route through the radiator.Paradoxes and Compromises
A very restrictive waterblock tends to be the most effective one as well. Same goes for Radiators. If you REALLY want to get cooling from your fans, you set them in Push, not Pull, but then they also make more noise. So it boils down to a lot of compromises or you might say paradoxes.The Heart of the Pump
Or rather, the Pump IS the Heart of the system. If your pump has the ability to generate a high flow
, and delivers high head
, you can introduce a lot of items to your loop, and use a restrictive radiator without killing the flowrate. In the last some years a lot of very powerfull pumps came into the scene with PWM ability which opened the best of all Worlds: silent running when possible but all the muscles when you needed it the most.
My favorite both because of the sizefactor, performance and the loads of 3rd party accessories like new tops, new cabinets to cool better, reservoirs and so on is clearly the Laing DDC in one of its flavors.
