Sounds like a pretty solid setup. What GPU are you using?
When I was looking into building a PC long ago (before I got my Alienware) I considered the 4790k. Despite being a few generations old they are still more than capable as processors. Most games aren't really all that processor heavy, which is why ram, GPU, and storage are always more important. But I like to make all things overkill.
GTX 980, reference model. Got it for $315 shipped late last year and wanted to be prepared for my Rift CV1 the moment it arrived on my doorstep, which it did back in mid-May. The GTX 1070/1080 weren't out yet and were out of my budget anyway.
It's proving to be adequate enough at 1600x1200@95Hz (still missing my FW900 that could do 1920x1200@95Hz just as easily) that it should tide me over until Volta. Hopefully, by then, we'll either have DisplayPort-to-VGA adapters that don't suck compared to the built-in 400 MHz RAMDACs that were standard up through Maxwell, or I might end up with a G-SYNC display whose image quality I can live with.
But as far as games not being CPU-heavy go, DCS World and PlanetSide 2 are just two examples of games that are more than happy to turn your gaming experience into a slideshow even on a 4.6 GHz i7-4770K, and the former's already confirmed
not to benefit much from NVIDIA's new Pascal cards framerate-wise because it's just that CPU-limited. It'd be a vomit fest if not for the wonders of Oculus asynchronous timewarp, that's for sure.
There's also other games like BeamNG.drive and Warframe that also quite visibly struggled on my old Q6600 box, even pushed to 3.6 GHz, but which hum along smoothly on the 4770K setup even before I factor in overclocking. CPU advancements had come farther along in six years (2007-2013) than I'd thought, that's for sure, but they've really slowed down after Sandy Bridge.
I've gone almost three years on the 4770K now; let's see if I can get at least six out of it like I did with the Q6600 setup before I finally decided I needed an upgrade. I'm thinking it'll still be good when Volta rolls out in about two years.
hehe. I'd imagine a computer that advanced wouldn't benefit from RAM drives nearly as much as mine.
The thing with my laptop's cooling system is that the fan eventually started going crazy at the slightest provocation and would make scary noises. This went on, on and off, for a few years. This year it finally stopped making noise altogether. Usually, when it's pushed too hard, it will overheat and shut off before the fan even makes any noise. On rare occasions, the fan will go crazy, trying to cool everything down. Most of the time, thankfully, it stays silent without going haywire in the first place.
Sounds like the fan itself is starting to crap out, except you've stated that it's clearly still running. Could be overheating, could be a sensor issue, could be something else entirely.
All I know is that laptops have a bad habit of having baffling, hard-to-diagnose issues that don't happen on any other system, especially not my custom desktops.
For instance, one of my laptops
would not work with Windows 10 version 1511. Updates from RTM build 10240 would break the OS, clean installs would fail, and only when they finally brought out Anniversary Update version 1607 earlier this month did it actually work again! Every other system I had just worked in the meantime.
i7's are becoming more important as time goes on. More games are benefiting from them. Of course the 4790k is outdated now, replaced by the i7 6700k which will soon be replaced by the i7 7700k. Until Vulkan and/or DX12 fully take over, CPU bottlenecks will remain a real problem (IPC performance is what's really needed, not more cores and threads).
Sadly, Skylake isn't that huge leap from Haswell that I'm looking for,
and it doesn't look like it'll be easy to increase IPC from here on out.
Then again, I don't think we're going to get the kind of hardware needed to brute-force its way through DCS at a constant 90 FPS any time soon, and that's factoring in that DCS had its EDGE update finally brought out so it's running on DX11 instead of DX9. Even so, framerates plummet once you start doing gun runs on ground targets with all the dust plumes being kicked up or start flying toward an area with a lot of AI units shooting it out. There's only so much you can do about inefficient code when the days of doubled CPU performance year after year are long gone.
It's crying out for DX12 or Vulkan when the action really gets going, but that's only going to benefit particularly skilled graphics programmers who know what they're doing. Most of those sorts are going to be working on mainstream, general-purpose engines like Unity or Unreal that will benefit a wider array of game developers just from their being licensed out to people who can't be arsed to reinvent the wheel for basic game functionality, not some in-house flight sim engine.
