cpu reaching 93 celsius under load

[Magnus17]

so i recently upgraded from a 1050ti to a 3080 and since then i have been reaching 10-20 celsius higher temps when under load. 

i get that my 1050ti was bottlenecking my cpu and made it less stressed but 93 seems uncomfortably hot.

i havent tried running with the case open but i can feel the heat from the gpu when i open the case after a gaming session.

when i repasted the cpu last year with a be quiet cooler i stress tested it in cinebench to make sure temps wasnt too crazy and it hit 76 celsius at max.

so im just wondering how bad is 93 and what i could do to relief some of the heat?

 

and i know im on an old platform but i chose to upgrade my gpu before everything else since that was what bottlenecked me.

 

thank you for the help here are my current specs

 

cpu: i7-4790k

motherboard: asrock c266 ws 

gpu: MSI Suprim x 3080

ram: 4x8 gb 1600 mhz ddr3

psu: 750w coolermaster gx bronze

move the cooling cables away from the gpu same problem with me and when i moved the cables away from the gpu the cpu wasnt under heat stress anymore because the gpu would heat up the tube making the air hot sending it to the cpu thus, overheating.

Sticking to the topic of the cooling issue, if you could list your case make and model as well as the exact make and model cooler that would help to better diagnose.

93 C is fairly hot, is that under a full synthetic load or just while gaming?

This would only apply if OP is using an AIO liquid cooler and has their tubes touching the backplate of the GPU and is a very specific issue. We typically like to get more information before jumping to these types of answers. While the help is appreciated we would need more information to know if this is even an issue the OP could have. Everyone's computer is different and similar sounding issues could have many different causes. Posting replies such as these this quickly without the proper information could cause the OP to go on a wild goose chase looking into an issue unrelated to theirs as well as cause confusion.

its an old Lian li tyr pc-x2000 and a be quiet pure rock slim 2 cooler.

 

thank you

Ok, so basically a case with very little airflow. Easy test would be to remove the side panel and front panel and see if temps improve. If the temps improve with the front and side panels off I'd recommend modifying the case to allow for more airflow or just buying a newer modern case that has adequate airflow. Most mesh front panel cases these days are pretty inexpensive.

i have been debating a new case for some time but i really like the mini server style it has with so much space for storage.

 

would new case fans be an alternative or is it more worth it for a new case?

 

but i will test it without panels on later today and see how that changes the temps.

Also dont forget the 3080 has a passthrough cooler meaning hot air gets thrown into the cpu heatsink.

 

Typical poor airflow case + modern gpu design increasing temps

Even with great fans on it theres only so much room to get air from.

 

You can totally make the temps manageable in this case and with some creativity even good!

Regardless of case fans you're still going to run into cooling issues. The issue is how much Air intake the case has. You can get creative and modify this case to easily be able to pull in more air, it would require permanently "damaging" the front panel and possibly the side panel as well. Sometimes you can order custom front panels for these types of cases(if they are popular enough and available) if you want to go in another direction other than DIY modding it. Or simply leave the front or side panels off if you're ok with that. Personally, I'd go for a more modern case that has proper airflow. Or if I wasn't worried about looks or cleaning it more often I'd just leave the panels off.

so hypothetical if i can get the temps some what manageable with my panels off or make some kind of cutout it could be worth getting better case fans?

 

i believe its just the old stock fans thats on right now.

okay thank you for the help i will be looking into temps with the case open and ill be looking for a case that fits what i want but with good airflow.

 

im short on money right now so if it seems okay with panels off i might just rock that till i get my money up.

BQ PR Slim2 cooler ?? It's not powerful enough for a 100W+ 4790K fulll throttle, upgrade it (TR PE 120 or PS 120 are good cheap picks BUT not sure you have LGA1151 mounts with them...)

Looking at that case, IMO plenty of air should be moving through it. Open it all up and run a stress test (OCCT, for example). If you're still seeing temps like that the cooler simply isn't up to it or the thermal paste has turned into cement (its old enough). 

 

3x140's even through the vented edges should be able to bring in plenty of cool air, which is echoed by reviews of that case in period. 

 

I think you simply need a better cooler and fresh paste.

this is what i get with the 40 second cpu benchmark.

 

i repasted the cpu at the beginning of last year.

and i just ran a f1 23 benchmark with the case open (since thats where i first noticed the 93 degrees) and my max temp was still lower than 77 celsius on both gpu and cpu.

Oh thats pretty fine. Like as long as its not 100c all is goooood

yea i thought so too thats about what it got before installing the new gpu. so i suspect that the case airflow is not great and that the gpu is obstructing the airflow since its a huge 3 fan gpu that fits with not even a centimeter to spare.

Also because the cooler has holes in the back which means a decent bit of hot air gets thrown into the cpu coolers path.

 

A simple way to stop that is have a piece of pvc board you cut to size and basically you create a duct so that gpu and cpu airfloe do not mix

Depending on the card you can also control some of the fans on the gpu instead of all, turn the pass through fan down a little and the other 2 (which should come as a pair i believe if you can control the this way?) up.

 

Also up the case fans speed which will keep everything fed with cooler air, do you know these fan specs?

[TPCEA]

Take @PDifolcoand @GuiltySpark_'s advice and get a better cooler, and add some more fans, maybe do ducting like @jaslion suggested, too.

 

BTW, PDifolco meant the TR PA120 or PS. If you're on a budget and want a good cooler, TR is one of the best options as there are so many inexpensive coolers. If you have space, the FC140 and FS140 are also good options. You will need to verify compatibility with your CPU, though.
