I have the 2.5/AMD hooked up to a 4K monitor and using the internal display and it runs quiet all the time. I bought this refurb'd from a company that bulk buys these from companies where they are depreciated. It has some dings and dents but it functions flawlessly.
Got a tip for us?

This just makes me sad...
Are you connect via HDMI or Thunderbolt/Mini-Displayport? Does this make a difference?

Oh God, how is that possible? One FHD monitor makes my 2.8 model whine already (despite I downvolted it and disabled Turboboost, so CPU isn't under a suspicion).
It's like we are speaking two completely different models. Interestingly, I've read many reviews about the same noisy and hot behaviour and quite a few about silent and relatively cool one. That's too weird.
Let's check our systems. I've got:
MacBookPro11,5, Intel Core i7 2.8
AMD Radeon R9 M370X, ROM: 113-C5670E-945, VBIOS: 113-C567A1-006, EFI: 01.00.945, gMux: 4.0.20 [3.2.8].
MacOS 10.13.6 (17G12034),
Boot ROM: 194.0.0.0.0
SMC: 2.30f2
It's connected via Thunderbolt. In the office, it's connected to 2 QHD monitors. At home it's connected to a 4K. The laptop is to the right of the monitor(s) so MiniDisplayPort is preferred as it's the shortest route to the monitors.
MacBookPRO11,5
2.5 Ghz
Boot Rom 187.0.0.0
SMC 2.3Of2
MacOS 10.13.6.
AMD Radeon R9 M370X
ROM 113-C5670E-945, VBIOS 113-C567A1-006 EFI 01.00.945 gMux 4.0.20 [3.2.8]

I start feeling it's something weird with SMC. Because I accidentially went into situation when TG Pro and Volta can't control my parameters anymore for no reason. It happened after reboot.
I checked the SIP status and it's disabled as before.
I f*** tired of all that retarded system! A plain hate is all I feel

Oh God, I HATE APPLE FAN CONTROL POLICY!
I scorn it, it's the stupid-most think I ever stumbled upon!
Whatever I do which lightly uses the GPU this f*** retarded think blasts the fans to the 6000rpm despite it may be only 65-75C, and does not calm down until it's 55C. But when I override the fan rules with MacsFanControl or something else this scorny Cook's ***** simply throttles itself to the bottommost frequencies (0.8 ghz) after a slightest use while the highest temp is absolutely reasonable 75C and doesn't recover until it blasts the fans to 100% for a minute!
Oh.. I'm crying in hysteria! This disgusting whine is killing me in recent time, I can't live with it. I dreamt about this machine FOR YEARS, and what do I get?
I do regret, passionately regret I spent so much time and money trying to get the "best" notebook, it's awesome from every perspective but this fan insanity KILLS IT ALL. If there's no fix I simply sell it to get rid of that hassle and **** it, done, no more!
I can't believe it's considered "normal". Isn't there a fix?

Haha
After it throttles to 800mhz kernel_task starts killing it by using 500-700% for nothing. What a ****, Apple.
Same slowdown with Windows. Total and utter disgrace

If you are adventurous you can buy some nail polish and Conductonaut, open up the cases, remove the heatsink, paint the electronics on the CPU and GPU with the nailpolish and replace the thermal paste with (a very thin layer of) the best one available.

Actually I did it not once. But my previews 2013 MBP which I had for a little time didn't show great improvement after such procedure, it was 1-2C at most, and fans didn't slow down anyhow noticeable.
The biggest question for me is - is this a common problem/a fault of my particular machine or a "normal" behaviour?
And if it's a fault, how can it be fixed

I have a hard time believing that it's the 2.8 Ghz as CPUs are binned by performance. That is 2.8s run faster under the same thermal conditions and power that 2.5s run at. I would guess that most people don't run into this problem or Apple would have done something about it. We have cases of this listed here but MR is where people talk about their problems - people that don't have the problem don't talk about it.
I suspect that there some kind of hardware issue that was either original or developed or it was some kind of problem putting it together. It doesn't make your situation any better but I don't think that they could sell so many of them, especially into the corporate market, if these problems were ubiquitous.

Coming from a 2014 2.2 model and running them side by side for a while I realized that even though both had Turboboost deactivated and both ran on iGPU only that the 2.2 model (both 2014 & 2015 have the same Haswell processors) made no noise even under high loads (thanks to deactivated Turboboost) and always stayed below 60 degrees Celcius, the 2.8 GHz Model goes up to 80/85 Degrees Celcius and makes noise during macOS boot up.
The difference is more noticeable with Turbo Boost activated even though the 2.2 now makes some noise.
I was shocked to see that a little more GHz makes such a difference, but I guess in the future I will opt for the lowest CPU I can get.

Intel not being able to control their processor heat
I‘m looking forward to the quiet ARM times ahead 🥳
Edit: have you tried CPUSetter or Volta?

What’s your maximum setting you can undervolt without freezes/crashes?
I quickly tried it out... what are your settings to see results?

My max stable undervolt is -65mv. on 75 it crashes while idling. TDP is usually 35W max, TB off. This way it may go full speed with about 80C and works quite silently with up to 30% fan speed. With TB - 50%.

I had that exact same MacBook Pro for several months. It was a great computer but it did run hot and noisy. I ended up selling it and getting a mint condition 2018 15” model instead. It runs faster and quieter. It’s a 2.2Ghz 6-core model but it generally runs at 3Ghz, same as the 2.8Ghz 2015. I paid $1700 for it last year. The 560X GPU is a nice improvement over the M370, but I’m using an eGPU with a Vega 56 now. Thunderbolt 3 opens up some nice eGPU options.

Sad info.. Can anybody tell than, does 2.6 2014 model suffers the same or it's better in that regard? I'll be glad to know if it worth switching
The 2014 is offered with the same CPUs as the 2015: 2.2, 2.5 and 2.8. The 2015 has a much faster SSD though so I prefer the 2015 to the 2014. I have a 2.2 Ghz 2014 and a 2.5 Ghz 2015 and I like both of them. The 2015, though, performs better as it has a faster CPU, faster SSD and Discrete Graphics. They are otherwise the same.

I suspect that the highest spec CPU options on any given MacBook Pro tend to run hotter and therefore with the fan running louder. Intel processors automatically run in turbo boost mode when under load, constrained by temperature. The MHz rating on the chip only represents the minimum clock speed the CPU will run at. With a MacBook Pro I think it’s not a bad idea to avoid the absolute highest spec CPU option.
I thought that the 2013s could have GPU problems. I'd go with the 2015. I have two 2015s 13+15) and a 2014 and the 2015 is the best. I guess I wouldn't buy a 2.8 Ghz from some of the threads that I've seen here. I think that the 2013s have more potential for the screen staingate issues as well. I do not plan to buy any more of the Retina line though. The 16s fixed the issues of the Butterfly generation for me.

idk why everyone has issues. I deep cleaned a used one I got and runs at 50-60c doing normal stuff. This is not hot people.
1. Take apart clean the fans. Remove the screws and remove any lint.
2. Clean the inside
3. Repaste with thermal grizzle kyonaut.

With various tools I have it under control but the 2.2 and 2.5 GHz versions run much quieter and cooler than the 2.8 GHz version.
2.2 GHz with iGPU runs quiet/cool with external graphics.
Having „upgraded“ from a 2.2 iGPU to a 2.8 with AMD I should have stayed with the iGPU and taken an eGPU for stationary use instead.
I learned my lesson. In the future I will go with the slowest processor offered.
