Annoying performance drop in PC, can't figure it out. Heeelp!

Hi everybody.
So, yesterday I decided to do my chores like a good boy and while doing so I moved my PC (while shut down and unplugged) a few inches to the side and cleaned the front mesh over the intake fans. After powering back up I noticed increased noise (it was howling) and increased CPU temps on Corsair Link and HWinfo.
My temps are usually within the 20's while idling with spikes up to the 50's for a second or two at a time... pretty normal... but now they sit anywhere up to the 40's idling with spikes going into the 60's but for much longer, a half minute or more at a time. They do eventually go back down to the 20's eventually but only after it's been on for half an hour or so. Still, it's all within safe parameters.
But worse still, gaming performance has taken a huge hit...
I was getting 60 fps maxed out in TW: Atilla, now in the 30's average (I have to drop to the performance preset to get close to 60 fps. TW: Warhammer is now getting around 70 fps compared to the mid 80's previously... and CoH2 is the strangest, registering in the low 20's when I used to get well over 60 but the in game benchmark tells me 20-ish is the low and 150 is now the max but it's not registering on Afterburner and it sure is not what I'm seeing. Doom on the other hand is only seeing a drop of maybe 10-15 fps... weird.
The only thing I can think it could be is the fact I force shutdown my PC after it hung up on 'configuring windows' yet again when I tried a normal shutdown.. btw it does this hang up thing often, it would still be configuring windows after several hours if I left it... I know, it's done it before and I've force shutdown before and it's been fine. Could this be the issue?
Anyway, I've run through a bunch of checks... physical hardware all fine, uninstalled drivers and the latest windows update to see if they were the problem (they weren't) and even reset the BIOS (which was basic, only the XMP was enabled) and still the same.
My PC has an i7 6700K, GTX 1070 (neither OC'd) 16 Gb RAM running a 2560x1080 screen btw.

Any advice or help would be very much appreciated, ta.

PS: Another older issue (but not as annoying) that I just remembered... I have never been able to complete a benchmarking run on Firestrike or Unigine Valley/Heaven. Firestrike just stops with the message that 'user cancelled the run' when I didn't and Unigine just crashes. Any ideas why?
 
Solution
Start with a fresh installation of Windows, one that shuts down properly and gets important updates installed. seriously doubt you did anything moving it.

Thanks. I figured that might be the next step. I'm going through the Win 10 reinstallation right now and I'll reinstall the relevant gaming/hardware related apps straight after. I'll let you know how it went as soon as it's done and I've tested it.

Ok, Windows is reinstalled/refreshed... I did took the option of doing it through Windows (a new thing apparently) It didn't take long. The third party software, Steam and games took much longer.
Anyway, good call on your part so thanks... I would've tried the Windows reinstall eventually but would likely have lost a couple more days (and hair) doing so when this has fixed it very well. CPU package and core temps (as monitored on Corsair Link and HWinfo) are now a little lower than they were when the PC was first built and average fps in at least a couple of games are 4-5 fps higher too.
So I'm still learning... did I mention this was my first build? I'd been saving and planning for this one for years and making do with laptops for that time (as I moved around a lot more until I became chronically ill 2 years ago)

You seem to know a bit more than me (I'm good at putting parts together but not at the stuff that makes it all work together) so I'd like to ask a couple more questions if I may...
I plan to do some further possible tweaks/upgrades on that PC this year... swapping the exhaust fans for RGB ones, connected to the fan controller (my case is a Corsair 460X RGB) also a GPU upgrade to a GTX 1080ti or maybe Vega if it's comparable (I want to go high refresh rate 1440p or 3440x1440) and will also need to reapply thermal paste later... will I need to reinstall Windows for any of these... and if I do could I save having to reinstall everything from my storage drive by removing it first?
When I did the reinstall yesterday I noticed after that a copy or image of my previous setup and apps had been made on my boot drive (an m.2, both drives are m.2's at present) alongside the reinstalled Windows. It's taking up 35 Gb that I can't spare... is it safe to delete and if so how?

Sorry for the extra questions btw... I'm just eager to learn to do this stuff for myself and do any upgrades or my next build myself... and maybe one day do a gaming build for my best friend who's more than earned it by sticking with me through some hard times. Also, this PC building/tweaking thing is addictive.
Again, thanks a ton for your help and any advice you can give me.

The other tweaks will not require a reintsall. Might consider looking into performing a regular backup, save having to reload everything. If you don;t need that extra image it can be deleted, windows like to save stuff just in case.
