[SOLVED] Overheating problem?

[PobesneliAbortus]

Recently I changed my PSU from CHIEFTEC ECO 650W to Antec HCG 750W full modular. I had no issues with CHIEFTEC, had no issues of PC shutting down due to overheating(PC actually shut downs system, and bumps fans speed to Max to cool down). When I replaced the PSU, under heavy loads it would do the overheating thing, even tho CPU and GPU dont go over 80-85 degrees. Does anyone have any idea how to diagnose or solve the problem?



My components are:
MBU: Gigabyte A320m-H
CPU: Ryzen 5 3600
GPU: AMD Radeon RX 580(8GB)
PSU: Antec HGC 750W Full Modular

Well, if you know that you have overheating issues then it is clear that your PC cooling isn't sufficient enough. Btw, 80C for GPU is A LOT and i'd avoid GPU to go anywhere near that mark.

To improve your cooling, you need to look towards:

• what PC case you have
• how many case fans you have
• what those fans actually are
• what are fans orientation
• is your PC filled with dust

Without knowing all the above, it's next to impossible to tell what you would need to do, in order to keep your temps within reason.

It could be as easy as cleaning the PC from dust and increasing fan speed from BIOS. Worst case scenario is that you're looking towards new PC case (if your current one is way restricting) and system swap + new, high-end fans for optimal cooling.

The matter of fact, this problem has been happening after cleaning my PC from the dust(when I put new PSU I cleaned the PC from dust as well). Fans on my GPU are working around 50% on the lower temps, bumping them up to 90% when GPU gets under heavy load. Since my case is old, only way air can circulate is through the back of the case and its left side. I have 1 rear fan that is putting out the hot air from the case(fan is working around 1000rpm, 120mm some cheap Mark)


As I started, this problem JUST came when I replaced the PSU and cleaned PC 2 days ago, and had no issues with it. I was thinking about chaning thermal paste on GPU and the thermal pada on it as well.

Well, you stated above something else:

I had no issues with CHIEFTEC, had no issues of PC shutting down due to overheating(PC actually shut downs system, and bumps fans speed to Max to cool down).

Based on that, i read: you had overheating issues before, but with Chieftec PSU, your PC shut itself down, to cool itself. While with new Antec PSU, your PC doesn't do that anymore.

Did i get it right? Or not?

I see I didn't wrote it quite well, sorry for the confusion m8. With CHIEFTEC I would've occassionaly experience overheats shut downs due to me not cleaning PC case and parts for 3 months. After that problems would be gone. When I put on the Antec PSU and cleaned PC parts, it will, inevitably after 5-10 minutes of playing GPU intensive games(AC Unity in my case, 1080p gameplay) that it would shut down due to overheating. With AC I never experienced this, even with 1h+ sessions.

My concern is that, because some dust was stuck onto the thermal pads of the GPU, that this is happening. Or there may be some software issue, or(tho I highly doubt it) that I got a faulty PSU from the retailer.

Hopefully I cleared the inital confusion I caused, sorry for it again.

Since my case is old, only way air can circulate is through the back of the case and its left side.

That kind of case is best to be scrapped, where new PC case, with far better airflow paths and fan support would be bought.

My best advice, without spending extra money, would be: remove the side panel of the PC and keep it open at all times.
Since one 120mm exhaust fan, at 1000 RPM, is nowhere near enough to exhaust all the hot air your CPU and GPU combined produce. And with enclosed case, air in it will heat up fast, like in an oven. With side panel off, there is far more room where the hot air can escape, thus keeping your PC internals from burning up and closer to the ambient temperature.

Or there may be some software issue, or(tho I highly doubt it) that I got a faulty PSU from the retailer.

Only "software issue" that can cause overheating is overclocking. Underclocking will reduce heat output but it also reduces the performance of CPU/GPU.

And i doubt that your PSU is in fault since what you have, is a good quality PSU, made by Seasonic. If it's 80+ Bronze unit then it shares the platform of old Seasonic S12II series (best group-regulated PSU ever made) and if it's 80+ Gold unit then the platform is shared with current Seasonic Focus+ series PSUs. (All 3 of my PCs are also powered by Seasonic, full specs with pics in my sig.)

Ye it is 80+ gold PSU. Thanks for all the advice m8, really appreciate it. I'm probably going to get new case after the holidays here are finished, and I'll see if removing the side panel will fix the problem for the time being.

Yet again, tnx for the fast responses, really appreciate it <3.
