Is 80+ degrees c normal under 100% load (rx 550 4gb)

ahnafspyro · Jul 4, 2018

So pretty much I got a new pc (HP Pavilion 580-137c) and the computer is great it can run the games I play, I downloaded a program to see my temps for cpu/gpu my cpu temps are good (35-40 c) but my gpu temps are 47-50c idle and up to 80-82c in 100% load. I was just wondering if that is to hot for my gpu, it gets that hot in games so simple like minecraft.. (and the gpu fan spins really fast under 100% load)
Also the psu is a stock 300w HP one I was wondering if I change it to a 400w EVGA one will it help?

That is pretty warm for a small GPU like the RX 550. To be sure though, what is your ambient temp? Also, what model of RX 550 do you have? Does it have an active cooling solution (does it have a fan and heatsink?)

If your ambient is pretty normal, then I'd suspect you have very little case airflow. Furthermore, I'd suggest installing a secondary program to ensure reliable temp readings. HWInfo64 is a reliable tool to use. https://www.hwinfo.com/download.php

Normal operating temp for the RX 550 is below 60C.

its about 80 degrees f in my room, and yes the gpu has a fan and heatsink, I have a stock RX 550 4gb, it came with the pc, its not like the one you get from asus etc

Stock blower style GPU's are generally designed to run at 80-83C. If it's running cooler, they usually just lower the fan speed to keep it at that temp under load. The benefit to doing this is to keep the fan quiet, as the GPU can handle the temps just fine.

You might want to check to make sure there is good airflow in the case. Those prebuilt machines often have terrible air flow, making them run hotter and louder due to what I mentioned before.

I don't believe they make a blower-style RX 550; unless HP has made their own. Does it have a blower-style fan? If so, then I would expect that to be normal operating temp given your ambient.

Alright! but one last thing do you have any tips for better air flow, its a pretty small case, and no space for cable managment, plus theres only 1 case fan

ahnafspyro · Jul 4, 2018

volkgren :

no its not a blower style fan

bystander · Jul 4, 2018

Get a better case, or at least try to manage those cables. Perhaps even adding a fan. If you show us a picture, it might help.

here you go, sorry for the bad picture, this where i got it from also: http://www.microcenter.com/product/503298/Pavilion_580-137c_Desktop_Computer_Refurbished

Looks like the case layout is not designed for good airflow. I'm wondering if your PSU is exhausting air outside your case? Updrading the PSU to one with a bigger/better fan could possibly help some.

I'm guessing though that you are experiencing normal operating temps for that setup.

Alright thanks I was wondering if I should upgrade my psu to a EVGA 400w one and the psu is blowing hot air out

Karadjgne · Jul 4, 2018

Psus will always blow air out, and not back into the case, they run too hot and that would be a minor disaster. What's important is where it gets the air from. If the psu fan is on top and getting air from outside, it's doing your pc no good. The psu would be better 'upside down' and pulling air from inside the case. This'll act as a airflow exhaust.

If the pics are right, that case fan is on the bottom, and as an exhaust is next to useless as heat will rise, not sink. In many old systems the psu was on top and acted as the only exhaust, with the fan facing the cpu cooler. With that lower fan, I'd make it into an intake, not an exhaust and blow cool air in from below and let the psu exhaust the hot air out the top-rear.

volkgren · Jul 4, 2018

I'd go with one of a new 450W Bronze unit from EVGA if you are looking for something cheap. I think it will do a better job than your current PSU at exhausting hot air out of your case.

*It looks like the PSU you have has some holes for exhaust INSIDE the case. This is a concern and a reason why I think the EVGA PSU would do a better job. If those holes do not let air escape inside the case, then a new PSU might not help much.

The place where the GPU fan is has a dead pocket of air. It's not going to do a good job keeping it cool. It might work a little better if the GPU was facing down, but that motherboard layout puts the GPU facing up.

Karadjgne :

Ohh! so if I switch the sides of my case fan (flip it) it will take the air from the outside and put it in the case?

Karadjgne · Jul 5, 2018

Yep. Your case is one of those upside-down ATX cases, there's a few around, so you have access by the right side panel, not the more standard left. Your biggest issue is airflow, you have really, none. What you have is a slight vacuum created by the low fan and possibly the psu, which will pull outside air in from wherever. It's not very efficient as those fans have a limited amount of draw area, so you get a lot of space that heats up, yet goes nowhere, just sits and cooks. By making at lest that bottom rear fan into an intake, you'll force cool air in, pushing towards the front of the case, picking up the heat and creating a small breeze, look just like a C. Air in bottom rear, curve around the front and back out the top rear. It's about the best you can do.

Karadjgne :

Thank you so much! I went from over 50 c on idle to about 35-40 c ! and for 100% load its now 70-75c instead of 80-85

Karadjgne · Jul 5, 2018

When you get a spare few $, get online and look for a magnetic dust filter that'll fit over the fan. It's not necessary as such, but since you now have a full intake fan, dust will accumulate quicker, so you'll need to clean the pc more often. The filter is more for convenience than anything, but a dead giveaway that the pc needs a good clean is when overall temps start going back up. Being magnetic, it'll just stick right onto the back of the case.

Is 80+ degrees c normal under 100% load (rx 550 4gb)
