rx 480 nitro+ overheating questions

Zombie_Trump · Nov 18, 2016

So Black Friday came around, and I was really hoping on getting a gtx1060-6gb, however, being tight on budget, and the Sapphire nitro+ Rx 480(8gb) having a way better discount and deal overall where I leave, I made the rash decision of buying that along with a brand new rig, made from pieces.

I'm no expert on computers, but I saw a lot of people talk about this rx480 as having some heat issues, and going above 80*Celsius if not well ventilated. I am curious if i have made a mistake, since I am planning on keeping this card at least 3-4years.

The Psu i got is Seasonic S12II-620 Bronze 620W. And I'm confident it's strong enough to power anything. However I have doubts if
1. the MSI b150m-Mortar Mobo is safe(wont melt or anything with this particular hot GPU) or
2. The Zalman Z3-plus Case with 4vents/coolers included is enough to keep the GPU cool(along with those 2sapphire ones on the card) or I would need some extra cooling help

I appreciate anyone who's knowledgeable on that RX480 or cooling to pitch in with their oppinions on the matter. Thanks a million.

What temps are you currently getting while gaming? 80C is warm but still well below the thermal limit for damage and won't even throttle at that temp. You could create a custom fan curve using a program such as MSI Afterburner to keep temps down.

It has not arrived yet, and I ordered a full rig with what i specified above, I'm just worried from all the negative comments sorrounding the rx480 heat issues. I'm curious if there is a genuine concern over this, or i should feel safe with a 4-vented-case and the Sapphire nitro+ rx480 http://www.pcworld.com/article/3098825/components-graphics/sapphire-nitro-rx-480-review-polaris-rethought-and-refined.html

For a AMD card it runs pretty cool, I wouldn't be concerned about temp unless it starts hitting above 90C which it shoudn't unless you have a really high ambient (room) temp.

I have the Nitro+ OC and I've undervolted it. Mine doesn't go higher than 60-62 degrees at ~35% fan speed in stress testing. You can see my specs below and the setup I'm running the GPU in.

The card is supposed to reach up to 74-75 degrees celcius in normal living room temperatures, anything higher does indicate something wrong.

As said above, you can undervolt the GPU and win 10 degrees of cooling pretty easily. The RX 480's ship with higher voltage than needed.

idk how undervolting works or what it is, but I wouldnt mind noise(ramping up fans), and ill make sure to get the trixx when it arrives and set it as cool and safe as possible, thanks, i hope when dx12 becomes more popular, I'll laugh at ever doubting this card haha

It's a great GPU. Undervolting is advisable for every RX 480 user since Polaris GPU's undervolt really well in general. What does undervolting mean? It's simply lowering your GPU's voltage without changing your GPU's clock speed and then running a stresstest (3DMark Firestrike I use) to see if It's stable. This lowers power draw, fan speed and makes the GPU run more stable in performance overall, It's more efficient.
