Hello all,

I shall be moving up to Ryzen some time in the fall. The system I currently use is a second-hand hand-me-down from a friend who originally bought it new from an eBay 'custom computer' seller. As such, the system itself is reasonable for what I use it for, but the case is absolute trash, and so I will be replacing it with either a Fractal Design Define R5 or R6.

I will be buying an Enermax Liqmax II 240 to cool the current CPU, and the Ryzen CPU. I'd really like a quiet system, hence going for the Define series in the first place, but in using a top-mounted radiator, with the newer Define R6, the ModuVent top cover is one large piece, while the ModuVent system in the older Define R5 comes as four separate fan covers.

I am just wondering how the AiO cooler would work with the Define R6. For the best cooling and noise balance, the Define R5 looks like it's the better choice, but perhaps I'm missing something with the Define R6. Ideally, I would like the newer case.

Are there any Define R5/R6 owners here who can shed some light on this dilemma?

Thank you!

The R5 is indeed the better balance. It is also quieter, made with thicker metal. The choice is up to you. They both have excellent airflow and cooling, so don’t let them being tight and sound dampened deter you.

The R6 is a little more modern-oriented, but my choice would be R5 because it is built like a tank.

Hey man, thanks for responding.

My only real concern with the R6, is whether it's possible to have the radiator installed at the top, while covering the remaining parts?

I know that is entirely possible with the R5, and just like the R5, there are four separated cutouts for fans, but can you cover up two of them and place the filter over the top? I think ultimately that is what I want to know, as it looks like I can't use the radiator in the rear half, with the top cover applied.

Possibly the biggest drawback of this revision, to be honest.

Also, I'd be going with the tempered glass version. Any idea how much this will affect acoustics, if at all?

Actually, it’s two different options with the top. You can go all closes and soundproofed on top, or all vented and filtered.

It’s one of the reasons I prefer the R5, because I can go one of each with the openings.

As to the glass, yes, it will be less quiet, but only a bit. These computers are not silent, just fairly quiet.

Okay, TH's review shows that the glass panel is still pretty quiet at 31.4 dBA (100% load). Honestly, I think I'm putting too much thought into that. I think the glass panel will be fine.

An alternative solution for the radiator, is the single 120 mm Enermax Liqmax II 120 in the rear as an exhaust fan. What are your thoughts on that? My original plan was the 240 mm version at the top as an exhaust. The case already comes equipped with two front fans (and a rear fan, but I will remove that if this solution sounds reasonable).

I notice that Enermax lists both versions as 96 ft³/min, which doesn't quite make sense when the number of fans changes. My concern with the single fan solution is simply how much it will impact the cooling capability.

Edit:
Just saw "no RGB lighting" as a con in that TH review. Really...? :rolleyes:

Okay, thanks guys.

Define R6 and a radiator in the front, it is. :)

One final thing; what are the differences between the Corsair Hydro H115i Extreme and H115i Pro? They are both currently the same price on Amazon. The only immediate difference I see, is the pump.

I also can't help but notice that on Corsair's website the fan airflow appears to be half of what it should be for the Pro model in the spec table (104.65 ft³/min for Extreme vs. just 55.4 ft³/min for Pro).

Which one would you go for? I may ditch the Enermax cooler.

The Pro is quieter due to the fans. They don't have much static pressure. If they are the same price get the Extreme and use PWM header on your Motherboard to control fan speed to your liking.

Better to get a higher pressure fan and set it at lower RPM. At least from my experience once you go past 1000 RPM you'll start hearing the air move.

CPU header on Motherboards can go down to 20% Cycle on PWM where the other headers only go down to 60% Cycle. Keep that in-mind when connecting and try'n to controlling speeds for low noise.
