Cpu reaching 100 degrees

[Manualkiller00]

Hi guys my entire system has been getting really hot since i have upgraded my GPU from a gtx 1070 to an Rtx 3080 before the upgrade my temps was fine. Playing games like csgo or low demanding my games my temps all sit around 70 degrees but higher demanding games after say half an hour my 3080 sits at high 80s and my cpu sits at 100 degrees and then i turn the game off to stop it getting higher.

 

Specs 

Mobo: Z170 pro 

Cpu: i7 7700k (not OC)

Psu:cooler master 600w (i know psu needs upgrading is in to do list) 

GPU: Msi Rtx 3080 10G

CPU FAN: Cooler master hyper H412R

fan setup: 3 intake fans at front, 2 outtake fans at top and 1 at the rear 

 

at 1st i thought the glass front panel was suffocating the 3 intake fans and so removed it and replaced it with a mesh front which did make it cooler for longer but still too hot and then i added 2 outtake fans at the top of the case which has had little effect. I am going to redo my thermal paste tonight but i dont think its this as my cpu never reached these temps with my 1070. i dont know whether its the poor case airflow im tempted to get a new case with branded fans but want to make sure its not something obvious or other things i can try thank you guys any helps appreciated. 
 

here are some pics note that some are older as it still has the 1070 and the glass front panel but these have been changed to mesh and a 3080.

 

Notes

Psu is underpowered should really have a 750 minimum as the 600 is running at 100% pretty much all the time i am upgrading soon.

 

i am going to take it off the carpet as i know this is probably not helping.

 

all case fans are cheap and unsure whether to upgrade to branded

If taking your sidepanel off fixes your temp issue then your fans are garbage or the case is garbage (unlikely since the case seems to be mesh front looking at pics)

 

Cooler is pretty meh but the 7700k is just a hyperthreaded quadcore so it should suffice for non oc

If you don't plan on upgrading your CPU for now, I would get an AIO and place in the front in a pull configuration. Maybe arctic liquid freezer II 120 or 240? 120 would be best for getting more airflow over the GPU. Both would work better than your current setup. You could also consider delidding the CPU and keep your cooler. Also another note.

That 2-3 generations old i3 CPU is severely bottlenecking the RTX 3080, that means the PSU has it easier (the 3080 doesn't draw as much power as it should/could), the GPU produces way less heat (since it can't perform to it's full power) and you do have a bad time gaming because of the  huge framedrops, frametime spikes and stutters.

 

The case is fine. Upgrade the fans to something like the Arctic Cooling P12 PWM PST (0-1800rpm).

Upgrade your platform to use the GPU (this way it performs like an RTX 2060 to a 3060), and upgrade the PSu not to have issues.

i agree with the fans...would definitely recommend swapping them out for some branded ones. One thing i learned for sure is: Never cheap out with everything cooling related AND the PSU which brings me to my next possible advise...

 

I would change that PSU ASAP and if possible than go for at least a 850W or even 1000W if you can get one on sale (you know....futureproof etc). The 600W you have in there now maybe could also effect all the problems with themps your having since CPU and GPU are trying to get more und more power than the current PSU could possibly give them. I could be wrong since that 7700 isn´t that power hungry BUT the combination with the 3080 plus the 6 fans might very well be way too much for that poor PSU which could make your other components go crazy

still a good troubleshooting step tho...might also be a good thing if the thermal paste is on there for a while

NZXT, Corsair and be quiet never dissapointed me...but that is just personal experience.

holy crap thanks i never even realised that i thought that was pushing air out thank you so much and i was thinking of just getting a new case with some better fans and an AIO

thank you for your reply im going to be upgrading my setup as i cheaped out on my case big time and didnt get a psu good enough to handle upgrades which is a lesson learned for the future

 

im going to be getting a 1000w psu 

an Aio and some much better fans it may be costing like £600 and be overkill but im just thinking it will last me a long time what do you think of these parts?

NP, test it out and see if it solves it. I would recommend upgrading CPU and motherboard at some point, then you could upgrade case, cooler etc. at the same time

do you think my i7 7700k is bottle necking my 3080 as i didnt think that would add much to my gaming as i dont really do any editing or processor heavy stuff i think

its not a i3 its an i7 unless that was a typo but do you really think that its bottle necking that badly on GPUZ it says that my gpu is running really well and has only really thrown up PSU bottle necks here and there which i know about but not any cpu bottle necks

I wouldn't recommend getting the kraken. The software used for it is broken and cooler is overpriced, noise levels too high. Get a arctic liquid freezer RGB 360. (make sure you have space. If not, I would get the 240 version. Still performs better than the kraken and works with no software. Pump and fans is synchronized and directly plugged in to motherboards PWM header. You can get the P12 A-rgb fan in a triple pack for £35.

Yes it is, alot. Of course it depends on the game, but in CSGO for example, yes. If you play 1440p a little less than 1080p, still def. worth a upgrade. If you got the dollars (pounds lol), I would save up for the new 7800X3D, releasing next month for approx £450.

Ahh shit i didnt think my cpu was bottle necking at all and i had no warnings from GPUZ 

 

if i did upgrade my CPU i suppose id have to upgrade my motherboard aswell at that point i mays well get a new everything haha

I see  

Yeah might as well. That's why I recommend, just testing out your current setup until you want to upgrade. No need to upgrade if you're happy with how it performs.

I havent really got the money to be shelling out on a brand new cpu and mobo do you think a i9-9900k would be better as i wouldnt need to upgrade my mobo then and could keep me going for longer until i have more money

I have a 7700K, your cpu is probably overvolted like mine was.

Does your cpu voltage reach 1.3V and more ?

I did set mine at 1.2V max in the bios, (I could (probably) tell you how).

Found some discussion here : 

 

Undervolt your gpu too, it's easy using afterburner. Lower the power consumption around 1/4.

 

(Remember, I'm not saying underclocking, just undervolting. Same performance, less power)

 

After that, if your psu worked with an "overvolted" system, it will work better with a fitter one. You can probably shave 100W total.

 

And your fans, they turn or they don't. Only difference with different ones will be the noise.

Weird fan config though. Rear fan is pushing air against cpu cooler. Top fans steal cool air from cpu cooler...Probably it can be done better...
