I7 8700 cooler

To be honest you probably need to de-lid the 8700k. Mine had temps like that under load even with a big AIO cooler on it until I de-lidded it and used liquid metal.
It might also be your motherboard pushing too much voltage to the CPU and/or enabling MCE (Multi-Core Enhancement) without you knowing it. Setting some manual voltages might help you out.

Do you mean the 8700 (non K)? If so, yes, the stock cooler is rubbish and won't be able to keep it cool even during gaming, which isn't that intensive, so it used to throttle. I installed a Hyper 212 Evo last night (£25) and had a full gaming session and that keeps it well under 60 degrees even when gaming. The Hyper 212 Evo is rated up to 150W and it is fairly affordable so it gets a recommendation from me.
Not really. Depends on the usual ...
IE. the chip (silicon lottery), case cooling, CPU cooler, application of TIM, ambient temp etc. etc.
Mine does 4.9 all cores at 1.28v and on a Noctua NH-U14s (push/pull) even running AVX benchmarks (IBT/Prime 95 latest version) only hits mid 70's. In gaming I've never seen any of the CPU cores go over 50C.
I'd say to the OP, up your budget slightly and get a decent air cooler, these chips do not need an AIO cooler unless you are going for very high overclocks. Or if you want very low temps, as suggested, de-lid the sucker.
Good luck.
Here you go. My I7-8700K. running the latest version of Prime95 (AVX instruction set) on a half decent air cooler (after about 25 minutes). Though it's pulling slightly more than 1.28v (as expected for a power hungry program like this).
It will run higher than 4.9 But needs either big volts, or an AVX offset. And my motto is "if it isn't stable in everything, then it aint stable" (quite aware that other peoples opinions differ, as is their right).
Buy a decent cooler once and it should last for a fair few builds.

Should have mention this is for the non K version, so at the moment thinking Hyper 212 Evo or maybe the Cryorig h7, need to keep low on price lads, been spending far to much money on pc recently, also vcore not going higher then 1.2v so hoping is the **** box std cooler.
The Hyper 212 Evo is plenty for a non overclocked one. The Criorig H7 is a tenner more and you will get no benefit, may be a couple of degrees lower here and there.
It is on offer too:

Scythe Mugen another decent cooler.
Thanks for that info Mikeo. Is yours currently overclocked on air ? I have Hyper 212 Evo in my current build so I would recycle that until I can afford an AIO cooler.Here you go. My I7-8700K. running the latest version of Prime95 (AVX instruction set) on a half decent air cooler (after about 25 minutes).

Yes, overclocked on air.
Unless you are going for an extreme overclock (5GHz +), you don't really need the extra complexity of an AIO cooler in my opinion. The best air coolers are at least as good as the 240 AIO coolers. Though I appreciate that some people just like them, which is fair enough. The Noctua that I have does a damn good job and even when the fans ramp up {1500 rpm) they are reasonable noise wise. Under more normal loads (IE. Not stress testing etc.) the fans on the Noctua run at around 800 rpm and at that, they are inaudible with the side panel on.
But as usual, it's really what an individual wants and is happy with. I did look at AIOs for my latest build, but decided that to significantly improve over the best air coolers, I would need a top of the line 360 one and that would have meant a new case. So decided on a decent air cooler.
Good luck whatever you decide to buy.

Thermalright Macho, best £40 ive ever spent on a cooler, its a beast.
Well my new cooler has arrived, all fitted running on budget board H310 for now, but hold on what I forgot to do when fitted Hyper 212 Evo???............ my temps was hitting 96C.......

Yeah you got that right foil left on heatsink, only took me 2hr to figure this out
won't make this mistake again.
Anyway as I type this running prime95 temps for 30 min

Anyway why is the CPU running lower then 4GHZ is this down to board?

65W TDP limit throttle, under CPU BIOS section change all short/long term TDP limits to 150W, max CPU current to unlimited (256A) or highest it could go.
If board has CPU voltage control options you might be able to undervolt the i7-8700 by 50-100mv using adaptive voltage and a minus (-) voltage offset, can lower CPU power draw and heat significantly!
Be aware H310 boards have lower quality and/or lower VRM phase count compared to Z370 boards, plus no heatsinks on them, lifting CPU TDP limits will kill the board quicker if you run heavy AVX workloads 24/7, if yes please buy a better board.
If the BIOS has no voltage options it might still be possible to control voltage and/or power limits with Intel XTU: https://downloadcenter.intel.com/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU-
Be careful when undervolting using the Intel XTU software, too low voltage could mean windows boot loop, reinstall Windows...
