CORSAIR’ H100 was a landmark of the self-contained liquid CPU cooler revolution, and after nearly a decade we have seen numerous changes as the model has evolved and improved. Most recently, the Hydro Series H100i PRO RGB had been the premium 240 mm offering, with this new iCUE H100i RGB PRO XT providing enhanced RGB lighting effects (and a lower list price). While it was fairly easy with previous generations of CPUs for coolers to keep the flagship i9 processor well under TJ max (the maximum temperature a CPU can sustain without throttling) in tough workloads, this is no longer realistically possible on current generation CPUs (and the 13900K especially) without extreme cooling (or enabling power limits).

I would start by looking at this review of the H100x here. Now it really would have been nice if the reviewer had included the H100i Pro, but they did not. However, it does include the H115i Pro which is the slightly larger 280mm size. You can see the temp differences are a fraction of a degree even between different size units. That then suggests the difference between a same size unit (the 240mm H100i Pro) is going to be essentially non-existent. When it comes to cooler tech, we are all very much limited by the conductivity of the materials (CPU and cold plate) and not so much by small cooler differences. The increased cooling challenges posed by Raptor Lake mean that we’ve had to change some of the ways we test coolers. Some coolers were able to pass Cinebench R23 multicore testing with Intel’s 12th Gen i9-12900K when power limits were removed (although only the strongest models were able to pass that test). Most liquid coolers and all air coolers I’ve tested “failed” that test because the CPU reached TJ max in this scenario. I currently have the pull fans on a separate fan controller, but that is just a stop gap. I would like to run them with the push fans on the pump fan controller.I see now. On the H100x, you will have the pump wire going to one MB connection and the fans to another fan header. You will have full BIOS options, although the pump is meant to run at maximum 12v/100% all the time.

I've found information on all the previous models with respect to the max current of the controller and they vary from 1A to 4A. I didn't want to just assume it was 2A as the 4 fans together pull just over 1A (the two pull fans are the red RGB variant of the ML120 pro series rated at 0.299A). You clearly are not here for helping. And if you didn't know i already have specified my specs. It's right under my profile name; (fryzen's specs).

If you want to see diagrams or more detailed installation instructions, consult your cooler product manual. If you cannot find your product manual, you can use this manual for the H100i Platinum.Frankly, I don't think the idea that no one here has both coolers and 6 hours to burn for your pleasure is that difficult a concept to understand. Perhaps you should take a moment of pause. For someone who "already knows all that", you have a lot of questions whether you are aware of it or not.

In addition to testing Cinebench without power limits enforced, we’ll also be showing results when the CPU’s power consumption is limited to a more reasonable 200W. We’ll also show results at 125W for those who prefer whisper-quiet cooling, at the cost of some performance. For both of these results, we’ll show traditional delta over ambient temperature results. From there, proceed with your typical Hydro Series cooler installation (don't forget to plug in your power and USB cables).It made me slightly nervous that the two channels are pre-wired (not a port on the pump) and the cables are pretty cheap and flimsy. It crossed my mind that it might actually be a single channel split in the pump housing, but the spec sheet does specifically state two channels so that seems unlikely. While in the past a CPU hitting its peak temperature was cause for concern, enthusiasts are going to have to learn to accept high temperatures as “normal” while running demanding workloads with Raptor Lake and Ryzen 7000 CPUs. Modern AMD and Intel CPUs are designed to run fairly hot without any problems – up to 95 degrees Celsius for AMD Ryzen 7000 CPUs, and up to 100 C for Intel’s Core i9-13900K. Similar behavior has been standard in laptops for years due to cooling limitations in tight spaces.

It's got to be a 4A controller. So you should be able to run 2 fans to each header.Yeah, I did run across that as well. The Pro Xt is not listed, but as you said, these are CoolIt pumps. At first I felt safe seeing that historically CoolIt uses 1A channels, but out of an abundance of caution I thought I would ask.While a particular user may be able to give their relative and subjective impressions of one cooler or the other, no one here has both coolers, a test bench, and a relatively obscure 7 year old processor to give you precise temperature and sound data significant to you. You need to find a professional review of one or both coolers to get that data and try to find a relatively similar TDP processor for power to make the temp comparisons meaningful. I think that last part is probably a long shot, so any comparison with another 4 core will have to do. The temperature differences are going to small, one way or another. The fan installation can be done in multiple ways, but by default we would recommend having the fans mounted on the bottom of the unit exhausting air up through the radiator towards the outside of the case. If your system is already set up to have sufficient exhaust, then you can experiment with mounting the fans on top of the radiator where they can push cooler air from outside of the case down through the radiator. If you mount the radiator with the fans on the bottom, then it might be easiest to mount the fans to the radiator before installing the radiator into the case, which is what I did for this installation.
