Ok thank you so much for the long answer and all the tips and stuff. I appreciate it A LOT since i just want to learn as much as i can about OC. I use the same monitor for temps as you are using and asus has its own software that has like 7-8 sensors on the motherboard that i have an eye on. I have the corsair h100i v2 cooler and i think its great so far. It runs like 1500 rpm when the cpu is at load in games and in atreaatests it does run faster but not near 100% to keep the cpu under 70c (ive made a custom fan curve). I also have three 120mm intake fans at the front of my case (NZXT h440w) and the radiator is located at the top of the case with push configuration and then i have one 140mm AF exhaust fan at the rear of the case so i guess my airflow is good...?
Well do you think its worth performance wise to try to push my cpu to 4.9 or even 5.0 ghz or ia it too much of a risk or compromise with the temps or stability? Or should i stay where i am right now? Again thank you all for the answers!
No problem, I'm always happy to help someone like yourself that actually wants to learn
Firstly, be a little careful with ASUS's own monitoring software, in the past it's been extremely well known to be unreliable, giving much lower readings than what was actually occurring. In previous gens, ASUS boards used AI Suite and Thermal Radar, not sure what they call it now, but that software would show CPU temps up to a huge 25 degrees Lower than what was actually occurring, because it read from a sensor *Nearby* and not the physical core temps.
So just bear that in mind, it's always good to have multiple apps/software reading he same things as a fail-safe.
The H100i is a good AIO cooler, so your temps sound fine. When running AIDA64 and other synthetic stress tests, temps will always be 5-15c higher than real world usage, as that is their purpose, to push way beyond normal day to day running.

(The point at which your CPU will say NOPE! Too hot and slow itself down so not to be damaged)
, for a 6600k is 105c I believe, so obviously try not to hit that mark.
But it comes down to what *
You
* are comfortable with. Many people say;
"Never go over 70c or the world will explode!"
, others say;
"90c under full load or heavy gaming is fine stop worrying."
If you feel comfortable with 65c, then that's fine, your system will be very quiet and last *potentially* years and years. Or if you're comfortable with 90c, that's fine too, your system will probably be loud as hell, it will most likely still last you years and years.
Yet in saying that, it could go bang on the first day of using it even running at stock clocks and voltages, it may have an underlying fault.... You just don't know.
Go with what YOU feel happy with
But just to reiterate; "1.35v -1.40v is normally considered *roughly* the safe maximum Vcore."
As for case airflow; I would recommend you either speed up the front 3x 120mm intake fans and slow down the rear 140mm exhaust fan. Or disable the 140mm exhaust.
Because from what you described, you most likely have "Negative" pressure, which means the exhaust fans are sucking more air out the case than the intake fans are pushing into the case. Negative pressure results in air being sucked in through any and every little hole in the case, which won't have filters on, so you suck in dust and fluff.
Either speeding up the front intake fans or removing/disabling the rear exhaust fan will provide "Positive" pressure. So more air is being blown into the case hopefully through dust filters than the exhaust fans are sucking out, therefore the extra air needs to escape, which it does out through all of the little gaps and holes. This leads to a cleaner PC, less dust and less maintenance.
Hope this helps.

Waow than you so much for all the long and helful answers you are giving me! Ye its still called aisuite and thermalnradar and ive noticed that they are showing lower temps then other monitor software are so im keeping that in mind. I think ill try to push my cpu as far as it goes ta a max of 1.4 vcore and depending on the temps since i dont want my pc to sound like a jet engine haha!
As for the airflow i have my three intake fans turnd up to max rpm and i have a possitive pressuare when my system is on idle but when the GPU is on load it sucks in alot of air from the holes of the back of the case which makes it kinda dusty under it and i feel like it fills my case with alot of warm air (i have the asus dual 1070) therefore i got the 140mm rear fan on max rpm because i feel like the hot air has nowhere to go and will stay inside the case. Maybe thats wrong? I have my rear 140mm fan connectid with a 3-pin header to a hub that is powered by a molex connector so all the fans connected to it (front 3 120mm and rear 1 140mm) is on max rpm all the time. Maybe i should connect my rear fan into a fan header on the motherboard? The motherboard can slow down a fan even tho its a 3-pin fan by controlling the output to it? Am i wrong? Again thanks for the help!
Having the fans linked to a MOLEX connection ensures they operate at full speed continuously. This approach isn’t the best for noise reduction or extending fan life, as fans inevitably degrade over time—wearing out or producing increased noise due to grease buildup and bearing wear.
Connecting a 3-pin fan to a 3-pin fan header on your board offers two options: you can manage them via BIOS settings, typically setting them to Silent, Normal, or Extreme modes, which usually can’t be adjusted further. Alternatively, you may utilize Thermal Radar to create personalized fan profiles even with 3-pin fans, or employ compatible aftermarket software for more flexibility. This method generally provides better control and adaptability.
If you insert a 3-pin fan into a 4-pin (PWM) header, the default speed will be around 60%, limiting your ability to fine-tune performance. However, 4-pin fans linked to 4-pin headers can be fully adjusted.
Concerning airflow, open aftermarket GPU coolers are advantageous—they tend to be quieter, more efficient, maintain lower temperatures, and look better. The main downside is that they push heat directly into the case, raising interior temperatures. Standard "Blower Style" coolers, found on older cards now called Founders Edition, are noisier and less efficient, but they excel at expelling hot air from the back of the case. Each cooling solution fits different cases and conditions.
As long as there’s sufficient airflow through the case, performance remains acceptable. Under heavy load, internal temperatures will rise noticeably, but they should stabilize over time. Positive pressure has minimal impact on temperature control; it mainly aids in dust removal and cleaning.
@OP - ive nothing to add to this except to remind u that if your questions was answered and people have taken alot of time to help u, remember to select one answer as the best answer to say thanks and so people can see u are not still waiting for help.
