Story on why a need a new cooler, you can skip below the TLDR if you want.

Hey all, I recently got an i7-4790K and installed the stock cooler. I booted up my computer too see the temp at 210F which I disregarded at first since the fans were at 2300RPM which is what it spins at for 99F. So I booted the computer checked the CPU in task manager and great, fine. Booted a game and figured out only 20FPS no matter what setting. Checked task manager the CPU was throttling at 1.4GHz, alright? Time to check the cooler, I take the stock cooler off and figured out the copper plate with the whole aluminum assembly and pre-applied thermal paste was floating above the CPU the whole time, what the hell?

I compared the 2 stock Intel coolers I had one for my previous i5 and the current one for the i7, there was a notable difference in the coolers being the i5 cooler was clipped in but was able to move about freely up and down but the i7 cooler was tightly locked in place by plastic clips making it impossible to even touch the processor which was the problem. So I had to do some surgery / adjustments on the plastic part of the cooler (No thermal paste at the time can't use i5 cooler) and eventually got it to fit fine with temperatures reading now at 140F-160F under load.

I don't really like those temperatures, I would like something lower and the CPU sometimes has to throttle back a slight amount affecting FPS which is pretty annoying when you have to turn around and new assets are suddenly loaded for the first time, reducing the temperature may help.

I also looked back at the case cutout where you can see how the cooler clips into the mobo and man, that looked like trash to me, it looks so flimsy and unreliable for a stock cooler, it looks like it was about to fall out but you couldn't push the plastic pins in any further and it felt like the heatsink was barely touching the CPU but there was nothing I can really adjust at this point.

TLDR: Intel stock coolers are low budget and flimsy and don't adjust RPM accordingly to increasing temperatures even though it has 4 pins.

Okay so I have some questions about coolers in general. It must work with LGA1150 and I am working with the Azza Sirius case, the side panel is a beveled out about an inch so I have some extra clearance than some other cases.

1) Does heat pipe or heat pad technology work better for heat dissipation?

2) What is a good thermal paste?

3) Are spring screws or normal screws better for CPU contact?

4) Does the mounting backplate matter? Any reports of heavy heatsinks putting too much stress on the mobo?

5) What's a good cooling assembly you would suggest?

My response to the TLDR, you're wrong the fan does adjust and the temps you're seeing are way above average. The temps you saw at first were close to the maximum thermal acceptance of the CPU. It also leads me to ask if you managed to install the stock cooler properly since an improper installation can and will show the same issue you've stated. On another note, what are your full system's specs inclusive of your case? It seems to me like you tried to install the stock heatsink while the motherboard was inside the case...correct?

1| Heat pipes move heat away from source and pretty much all new aftermarket heatsinks are designed around it.
2| I use Arctic Cooling's MX-2 but you can pick up Cryorig's thermal paste.
3| The mount will vary...

3| The mount will vary per cooler and their makers since not all cooler mount exactly the same way nor does all the cooler in the market require the same amount of pressure and application.
4| As stated above some will need it while some don't. Some are necessary to achieve even TIM dispersion across the IHS and to get better temps. Yeah Thermaltake's Orb coolers were so large and heavy that it ripped the CPU socket off the board. With today's motherboard PCB being thicker and reinforced, you shouldn't need to worry about that :)
5| To answer that we'll need to know your full system's specs inclusive of the case since case clearance's can limit cooler height while the TDP on your CPU will also matter. When you overclock the CPU the TDP will increase which means we will need to factor in headroom. We also need a budget, your country and the site from which you'd like to purchase the cooler for us to source a viable candidate.
