Here's the plan; to overclock an i7 5960x to a stable, cool, 24/7/365 4.8-4.9 Ghz (definitely want over 4.7)

Here's all the hardware going in the build:
i7 5960x
ASUS RAMPAGE V EXTREME/U3.1 LGA 2011-v3 Intel X99
Corsair Dominator Platinum Series 32GB DDR4 DRAM 2800MHz C16 4x8Gb kit
EVGA GeForce GTX 980 Ti ACX SC+ ACX 2.0+ Graphics Card with Backplate 06G-P4-4995-KR
Creative Sound Blaster ZxR PCIe Sound Card
Intel Solid-State Drive 750 Series SSDPEDMW400G4R5 400GB PCI-Express 3.0 MLC
2x1TB Samsung 850 Pro SSD
2x1TB WD HDD
2x2TB WD HDD
EVGA SuperNOVA 1000 P2 80PLUS Platinum Certified ATX12V/EPS12V Active PFC 1000W PSU

Now here's my planned cooling:
Obsidian 900D ATX Super Tower Case
2x480 mm rads (I started a different thread about which is better, either Black Ice Nemesis 480GTX or Alphacool NexXxoS Monsta 480)
Twin D5 Pump XSPC reservoir
In a single loop through a EK-FB ASUS R5E Monoblock
8x Delta AFB1212GHE-CF00 120x38mm Grand High Speed Fans, @29 watts 240 CFM @ 29 mmH20 pressure,
Run on a Lamptron CF525 60W - 5 Channel controller. (It seems some don't recognize this controller so let me add a footnote; this is NOT a 60W controller, it's 300W with 60W on each channel having 3 molex plugs that recommends a 700 Watt PSU or better)
2x Delta AFB1212GHE-CF00 120x38mm Grand High Speed Fans on the front of the case
With finally w/e 3-5 watt fan I can slap on the back, also blowing in to try and have at least reasonable pressure going in the case (Probably a Noctua Industrial)

Footnote 2- before anyone says anything about jet engines and loud fans, I've lost most of my hearing, it would actually literally have to be a jet engine for me to hear it.

Finally, I know these CPUs are very easily taken up to 4.5-4.6 on decent 240-280mm rads with good ventilation on them, I've also seen them taken up around low to mid 5's on Phase Change cases or Water Chillers. From what I've read and a little from what I've seen, up around 4.7+ it starts getting much hotter than 280 or 360mm rads can handle. My biggest question is, am I going overboard with these fans? That's 300 watts just to the fans with close to 2000 CFM being moved through 2 massive 480mm rads. Is that overkill, should I just go with decent 3-5 watt fans or am I doing the right thing for my planned 4.8-4.9 OC. I would also like to add that I do a lot of video encoding so this CPU is going to be maxed out for hours at a time, often.
 


Well, might be fine then I guess.



I see, thought you were talking about video playback.

You did ask regarding your thread title:

IMO you are definitely going to overkill levels for standard radiator water cooling, you do not need that strong of cooling fans nor that powerful of a fan controller, I know of no other water coolers that are using 5200rpm 60decibel cooling fans, drawing a combined total of 294W and 24.5a, so that is definitely overkill.

However it really seems you have no intentions of changing your original plans no matter the information you get here, now if you want to really see overkill when it comes to water cooling, which is allowing my 5ghz daily overclock, Here It Is.

Edit: I am curious to ask this question?
You've made it crystal clear that the noise level the fans will produce is not a problem or concern for you, so my question is, Why buy the fan controller at all?
All you need is a M/B 4pin or 8pin to 4pin Molex adapter cable to run the fans straight from the power supply?
 


I've looked into your Peltier, as well as phase change and water chillers. None of them even come close to acceptable functionality as far as set it and forget it. Besides the fact that I don't want basically a damned refrigerator attached to my PC. If I wanted to go that route, I'd just order a nice phase change system or water chiller system, but I'm not even considering that option at this point. My two main towers, literally run, 24/7 year round, with the only reboots being the once a week/month for system maintenance/cleanings and the occasional system and/or software updates. Once it's running, I don't want to maintain it, except for at most taking it to the garage every few months and blowing all the dust & dog hair out of it. When it runs, I just run it as is until I fry it or just want something new, which has always been in the 1-2 year range.

You must live in a very-very quiet environment, or at least that's what it seems like from your aversion to fan noise. I literally live 2 miles deep in the woods, in a fairly lush and large house that is, to an outside observer, LOUD, always. Just to put it into perspective, I have a sound system that can be heard almost 2 miles away. I like to scare the forest animals with things like Ministry, Led Zeppelin, NIN and Rob Zombie. I have 3 guard dogs, I care for a pack of coyotes, my sound system and I'm not even going to waste my time itemizing all the countless background noises like TVs I leave on all over the house, the assorted music playing in different rooms, the sound from my main projector screen audio, the sound from my 84 inch UHD, etc, etc,... etc. I can honestly say I think you have no idea and from what I've noticed you can't even begin to imagine the sound setting in which I reside. Plus when the wife is home and/or my/her friends/family are over, countless other sounds added. I literally can not even stand absolute silence, it drives me over the edge. I've never even been able to sleep in absolute silence. Which makes me lossing most of my hearing now that much worse. Let me put it this way, a little 1 HP electric air compressor puts out about 60-70 dB. I have a 14 HP 120 Gallon industrial air compressor in my garage, that I seldomly shut off, for one, because I like to keep filled and I only empty it to drain the water every so often and two, because I don't hear it running. You said you left the room when you tested these fans. I'm not in a "room", I spend the vast majority of my time in this open floor that's 2500 square feet. You don't understand how sound dissipates in that much open space. Plus the tower sits in a side front open cabinet at my desk, that's about 25-30 feet away from where I usually sit. Plus if it's THAT loud, which I very highly doubt, all I have to do is enclose the cabinet, soundproof it and run air ducts to it from my home environmental control system that always pumps fresh & filtrated air down here.

Like I said, you don't know my circumstances. As for over kill, so I can be more explicit. To get my i7 5960x running at an acceptable temp, in a 24/7 stable 4.7-4.8, is it overkill to use these fans, because something like the Noctuas we mentioned would suffice as far as enough cooling, using the biggest and best pair of 480mm radiators. I've only played with 110-280mm closed loop cooling systems, that were fine for the OCing I did on my passed AMDs and Intels. Now I wanna go fairly big league, but again, on a 24/7 always on always used OCed PC. The one and ONLY thing that really bothers me and is the only reason I ask, is that it annoys the hell out of me to have to run 300 watts to little frickin PC fans. With my general negligence (I've had to clean everything from cigarette butts that fell and burned through the grill, to coffee, beer, brandy and mushroom soup outta my towers), meaning I just like turning on my PCs and using them till they fry and/or get replaced once they're set up. Making that much wattage to little fans just an electrical hazard/fire waiting to happen. So if I can avoid that and use the lighter weight fans, I'd be happy. 😛 LOL!

As for your controller question, besides the fact that I actually love switches and knobs, when I say stable and acceptable temp, I mean you know, even with all the cores maxed out, which for me will only happen when I'm encoding. If I'm not encoding redlining all the cores, I only really use about 20-30% of the CPU, so I don't really see why I would need to keep the fans maxed out, if they're not needed. I may be wasteful and negligent in too many areas, but when it comes to machines I'm a stickler about efficiency. These fans on my server is one thing, but in my little PC case it kinda gives me the willies. I know the wattage going on inside a PC case, it's just that much wattage to little fans in PC, kinda seems like I'm asking for trouble, if it's not absolutely necessary to get the cooling I want, the way I want. :)

To be honest, if you guys tell me, that two massive, fat 480mm rads on single loop to the chipset and CPU, with normal fans should hold, I will in all likelihood drop building it myself with a custom water cooling case I order and just get the Aventum II from DigitalStorm like that, accept their 4.5 or 4.6 OC (which they only originally do on 1 480mm rad, but they said they'd add the 2nd 480 rad intended for the GPUs and just not put the waterblock(s) on the cards), get the intel Tuning warranty and push it myself that little more to .7-.8. The irony there is like that, the prebuilt will cost about a 1K less than the home build I'm concocting. :heink:
 


I'm not really sure, what you're upset about this time around, but considering you were the first to jump in all gung-ho, when you didn't even know what the hell you were talking about, on multiple occasions, it would seem that you do care, at least to some extent. Too bad it's caring about nothing I ask. I tried to clarify to you the situation, because you keep going off on tangents, that I couldn't even be paid to care about. I'm asking, is it overkill to use these fans, if regular fans would work, for what I want to achieve. I know about all the other available cooling options. It's not like I just discovered PCs last week. I've been using PC's since the Commodore 64 days and online since 88. If regular fans work and I need just a little more, I can still have a 3rd radiator slapped to the front of the case, but I want to know, if the kind of cooling I want would require the massive CFM and Pressure of server fans. No offense, but you jump from two extremes, from simple stock fans to peltier and now you're butthurt, because I tried to clarify my situation for you? How about you get over yourself and stop trying so hard.
