Ok i did some stress testing with aida64... and only stressing cpu got 71-72c i stressed 3 mins and it was a pretty constant 72c. So then i stressed cpu and fpu wich got up to 89c and then i stopped the test cuz i didnt want something to brake. So i did apply the thermal paste incorrect now right? i have an intel core i7 4790 and intel stock cooler. I lifted the cooler to see if it spread and the whole cpu was covered with a thin layer but i heard when it heats up it spreads even more so too much right?

First, you don't need to worry about your Haswell processor at 89C It's safe to run up to 95C, at which point it will start to throttle and cap out at 100C unless you have disabled that feature.

That said, I was recently having major problems cooling my i5 4670k to the point I bought a much larger cooler for it (I was already on an after-market cooler, you should definitely replace the stock cooler regardless), which... only somewhat helped. My processor would hit max temp within about 2 seconds of running Prime95, and with the new cooler it would take about 20 seconds to hit max temp... not that great of an improvement really considering a cooler rated for 140 Watts couldn't keep up with a processor running at 100W. The air coming off of the cooler wasn't even very warm. Changing out the thermal compound between the cooler and processor only ever made a difference of about 2C for better or worse.

So Ultimately I delidded the processor using a tool from aliexpress that cost $7. I figured it is risky, but I would probably need to replace my PC regardless if I couldn't get the temperature under control. I have to say it was TOTALLY worth it. The Thermal Interface Material (TIM) between the internal die and the heat spreader had basically turned into rubber like an eraser for a pencil. I replaced the TIM with liquid metal (~$15) but I think even normal thermal paste would have made a big difference with as bad as it had gotten. The TIM in Haswell apparently has big problems when it gets this old.
My temps during gaming dropped from high 70s to low 50s, and my steady-state temp in Prime95 dropped from 100C+ (who knows how hot it would have gotten if it didn't throttle) to closer to 80C It was a drop of 20C-30C which is absolutely ridiculous. This is the reason so many people complain about Intel using TIM in their processors instead of solder. It becomes a real problem over time.

my first build was an i7-4790 - i'm running a noctua NH-U12S cooler and when i render videos on that rig, with cpu at 100% load i see 64-68C temps

as far as damaging that cpu - it's bulletproof. Intel has built in thermal limiters that totally drops the cpu's load at 100C, but to tell you how effective that thermal limiter is, for the first three months after i built this rig, i rendered video files, 1-3 hour jobs, 2-3 files a day. I was relying on Asus's AI Suite III perfromance monitor for temp monitoring and it always reported 67C, never higher. I happened to download HWMonitor and damn if it didn't report temps, while rendering, at 98-100C - it would hit 100C, fall back to 98C and climb right back to 100C, and keep repeating. I downloaded Intel's XTU, as it reports temp and the sensors are intel's, and it also showed 100C.

BTW, this was on the stock intel cooler, it's fine for web browsing, but i wouldn't use it for any serious work.

After correcting temps with a new cooler, in XTU it has a benchmarking utility, that once you run it, let's you upload the score to the web and compare to others running the same motherboard and cpu - everytime i run one, i'm in the top 5% of the population, score wise, so i'm pretty confident hitting those temps i did, didn't harm the cpu. Bear in mind, i had been rendering video files for 3+ months before discovering the Asus AI Suite III was crapware, and i'm still scoring benchmarks in the top 5% 3.5 years later

wow thx for answer and i just realized the ripped me off. They sold me this PC for 1k it has a 960 2g 16gigs of ram ddr4 and they called it "gaming pc" and gave me a <perfectly serviceable> stock cooler

Mod, watch the language, nothing wrong with a stock cooler, it keeps it cooler enough at stock.

we've all been there, trust me - call it a learning curve and next time research more before buying

put a decent cooler on it and you'll be surprised at how well that cpu performs

I agree, Haswell processors still preform very well when overclocked, because they have a very similar IPC to Ryzen 2. So my i5-4670k at 4.2Ghz performs nearly identically to a Ryzen 2600 @4.2GHz on any task that is optimized for 4 threads or fewer, which is a lot of games. Granted Ryzen performs way better at workstation tasks.

With decent cooling it should be no problem to overclock that 4790k to an all-core 4.4 GHz or better, which will perform very well for games. But it's stock settings (4Ghz with 4.4Ghz turbo) are still pretty good.
