H110GTX (5960x) vs Custom Loop Switch Experiences?

I've seen various/many people ask and answer this in theory, but wondering if anyone else had done it and what they experienced?

Anyone switched to a custom loop from an H110 to custom and what did you see in terms of temps?

@4.4/4.2 (core/cache) 1.27v Running heavy single core apps, I see 100% load core temps in the 45C range on a per core basis.

Running a full load on the system using all cores, I see sustained ~58-62C, but some peaks (a single print) at the start from idle at 68-70C. Package temp is 65-68C sustained (58-62 is core temp)

So, I know I can make it pretty. I know I can make it quieter. I know I can make it a heck of a lot more expensive.

What I don't know is if I can bring those sustained load temps down. I run these loads for hours (days) at a time, so if I could, I might be able to convince myself to do a custom setup, but not for 1C.

To make it worth it, I'd like to see:
1. These temps at 4.6GHz @1.3v would be interesting
2. sustained temps 5C lower would be interesting
3. reduced peak temp at job start (1-2 second spike) would be even more interesting
4. VRM cooling with a mono-block might be compelling in terms of fans (fewer case blowers - that heat moved to a larger radiator with slower fans).

So, what have you seen?

Well, I guess I'll be the test subject then... Read enough summaries of temps and cooling setups, I am reasonably convinced I should be able to meet some or all of my criteria with a higher volume of fluid and a larger radiator.

So, I ordered some parts.

I have seen that neither RealBench nor stressapp are actually indicative of the temps I've seen in my real-world application (I see HIGHER temps in my daily use than I did in RealBench and much higher than stressapp). So, it is possible the anecdotal evidence I've seen out there on "the internets" is not representative of my application. On the bright side, it will be quieter and pretty. 😉

Actually, pretty will have to wait, I am going to cram all this in the same 200R el-cheapo case for now.

Hello cekim, I'm limited on space with my case too so I just went with an external cooling unit (in my specs) and I'm getting great temps. I have my 6700k overclocked to 4.8GHz with 1.488v and my gaming temps are great. If you'd care to see come to the z170 Maximus VIII section my thread is "Maximus VIII Formula" - Nate152.

EDIT: Woah, you went REALLY "external cooling". 😉

That's what I did with the H110GTX - I cut a hole in the top of the case big enough to feed the AIO CPU pump-head through and mounted the rad/fans on top.

The 110 radiator just barely fails to fit inside this case. It presses up against PCIe power connectors and one of the caps on the board. So, outside it went.

My plan for now is to basically swap out the H110GTX for a 140mm 420 (x3) rad and a "monoblock" for the 5960x and its VRM. The rad and fans will be "mounted" on the top of the case in as ghetto style as is required for now.

I'm looking at other options to mod this case for something longer term or eventually I'll just get a proper case for all this stuff.

I actually have a 6700K as well with an H100i in the same case (same model - 200R, not the same physical case) - but the rad fits inside this case except for the fans. So, they are mounted outside with the rad inside.

Not bad so far. My concerns and hopes about VRM cooling hav been unfounded and fulfilled respectively (it is being cooled, it is not dragging up package temperature of the CPU so far as I can tell). Unfortunately, stressapp is not sufficient stress (compared to my daily driving), but here's the first data point with an EK 420 monoblock D5 combo:

(full-disclosure, I benchmarked my 2 5960x's after I started this thread and found the second to overclock better and run slightly cooler, but these pictures are on the same CPU at the same voltage and frequency. First is today's run with new EK system, Second is the prior temp data from the H110 run.

My experience so far is, works great and worth it but:
1. "bring enough gun (case)". The 200R worked fine for the H1xx with some easy mods, but even this bigger thermaltake thing was a tight fit with a long video card.
2. Holy barbs batman, I don't know if my tubing was a smidge thicker than spec or is it really supposed to require that much force to tighten the collar? Not trying to get it all the way down, just starting the threads tore my fingers up.
3. H110GTX is much easier and rather effective (as you can see, I've had good experiences with them, so I keep buying them)
4. speaking of barbs, at least initially, the collars were not required, the hose was tight enough to seal on its own. I assume that over time they'll stretch and I'll need to re-tigten
5. PWM pump does no like to bleed - you need a dongle to command it to pump in earnest. It will bleed without a PWM drive connection, but not without a LOT of help.
6. I bought a cheap big case V71, so no room to complain, but they seem to have threaded every hole with a rasp. Other than that, I am quite pleased wth it.

After and before (aka: moving day - this here, that there, the other in there now, musical parts...)
