Getting a high refresh rate monitor would not be the worst thing right now if you can afford it. Definitely go for a 1ms response time. they are common enough now a days. and if you shoot for a 144hz monitor you can keep the refresh rate at 60hz until you get a better graphics card down the road. this way when you upgrade you will immediately be able to use the benefits of having a better card. As far as the graphics card goes i personally wouldnt waste the money on a 1050. i would go for the new 1650's if the 1050 price range is your budget. they aren't any more costly i dont think and the performance to dollar ratio is just amazing with those cards. just dont fall for the pricier AIB gimmicked ones. just a basic 1650 will work. i think they even have a ti version

Without a proper calibration device your going to have to eyeball it using a calibration program or website.

Ok to put everyone to rest here, just by switching to a Better thermal paste and NOT resealing the heat spreader I dropped 20C on average. So yes the paste and sealing method does Matter

I have never used thermaltakes thermal compound, so I cannot attest to it's durability. The main thing to look out for is the paste turning into a chalky dust and cracking apart. If you are not resealing the CPU, I'd say go for it, and if you notice thermals getting worse over time, investigate the paste. While this article is old, it's certainly a good read and is applicable today: https://www.electronics-cooling.com/2007/11/reliability-testing-of-thermal-greases/
 
Most pastes are designed to perform well, and to be budget friendly while doing so, but not every paste is advisable to use on the die. It's just something to keep in mind if you run into further issues in the future. I certainly do not suspect your choice in paste to be causing you any issues at the moment, as it would take far longer for the effects of pumpout or drying to take place, and I've certainly never seen a paste dry up in such a short span of time.
 
So if it were me in your current situation, I would start with rocking the radiator to make sure no air found it's way to the pump, as that would be far easier than pulling the block off and removing the IHS again, and if that does not solve things, investigate IHS contact with the die, and visual characteristics of the paste (did it make proper contact, did it get good coverage on the die, is it still in a malleable form, etc). 

If you applied to much AS5 compound it could have insulated the die and caused the opposite effect as the the intended purpose of transferring heat away from the CPU. I use AS% myself and its a heavy compound so a little goes a long way. I've never delided and replace compound but I know this can happen even if you apply to much onto the heat-spreader so maybe, if you can do so safely without damaging the Die, try and remove compound and try putting less. Then again it could be you didn't put enough. Tough one. Good luck.
