Is this considered overheating?

Hey guys! So I got my hands on a copy of Hitman GOTY Edition! I'm running it on max graphics on my XFX GTR RX480 8GB Black Edition GPU! The game runs smoothly and very stable. Well..... My GPU temp was hitting 85C! Is this anything to worry about? I set a custom fan curve that's very aggressive, running my GPU fans at 95% when hitting 80C, and that has kept my temps down to about 80 - 81C. But is mid 80s bad for this GPU?

For max settings, that's probably about right if you are at or above 90% GPU usage. Any higher than 80°C and something is not right. You may be lacking in sufficient case airflow to deliver enough cool air to the graphic card so that IT'S fans can use that cool air. If they are cooling with warm air due to poor case circulation, then higher temps must be expected.

Up to 80 is normal. Above that is not.

Cool thanks for the reply! Is 85 pushing it? Without a custom curve, it's 85C. My worry is wearing out my GPUs cooler running it crazy with the fan curve I made. Although, my GPU has detachable fans, in THEORY, those could be replaced pretty cheap.

85 is pushing it. Actually, it should probably either already be throttling at 85° or soon after. I'd set the fan curve to be at 100% by the time it reaches 80°C. Or sooner if you can stand it.

As I said before, case cooling plays a huge role too. What kind of case fan configuration do you have? Case model? Number of fans? Intake and exhaust configuration? Makes a difference. A 10% increase in case fan airflow can equal as much as a 5°C difference in CPU or GPU temps if everything else is optimal, so an additional fan or a slight increase in case fan curve can significantly drop the amount of work needing to be done by your GPU cooler in some instances.

You can determine if case airflow is contributing to the problem by removing the case side panel and checking to see if you still have similar thermal issues or if there is any improvement at all with the side panel off.

It most likely is bad airflow. This is the PC that I bought https://goo.gl/TJ4mAA I DID change the power supply and GPU since I got it, so my specs are a bit different. I changed the intake fan on the front with an Enermax tb Vegas fan. The back exhaust is the one it came with, probably some super generic fan. Would changing the back fan help at all? Maybe another Enermax tb Vegas? Or is there another great fan you recommend? A louder fan doesn't bother me too much, my whole build is kind of loud lol

Aaaaaiii!!

Sorry, I was afraid you were going to tell me it was something by iBuypower or CyberpowerPC.

So unfortunately it seems to be the case that most of these older style iBuypower cases do not support extensive cooling options. Here are my two recommendations and I doubt you're going to like either of them but it is what it is.

One, run the system with the side panel off. The CPU and GPU coolers will cool as well with the side panel removed as with ANY amount of case cooling for the most part. There will be plenty of fresh, ambient air to supply them with as cool a supply as would be available any other way. Contrary to popular belief, fans do not reduce temperatures, they merely help to move heat elsewhere, making it SEEM as though they are cooling below ambient when in fact they are merely helping to equalize DOWN to ambient temperature. So, removing the side panel will allow you to see basically the best your current CPU and GPU cooler can offer.

Two, get a different case that will afford you some better fan location options if running the system with the side panel off is undesirable due to noise or environmental concerns like moisture or dirt/dust.

Considering that system has a pretty low spec CPU compared to what's available even on budget offerings these days, you might also entertain upgrading the CPU, motherboard and RAM in the not too distant future as what you currently have are certainly holding back that card from getting the best possible experience it can offer.

I have definitely gotten that reaction before not gonna lie! Haha are they just that infamous? LOL there are however 2 120mm fan slots on the top of the machine with no fans, I'm even thinking of putting 2 exhaust fans up there. Might help my issue a bit but not too sure! The motherboard and CPU is DEFINITELY next on my list! It's currently my weakest link in this build. If even after getting top exhaust does nothing, I might just bite the bullet and get a new case, moving everything over.

Darkbreeze · Nov 13, 2017

Yes, if you have two exhaust fan locations at the top of the case then I would definitely recommend making use of them. It will ABSOLUTELY help with ALL internal temperatures.

Do you know what the model of your motherboard is? Kind of need to know how many fan headers there are on the motherboard and whether or not they are voltage controlled 3 pin or PWM 4 pin headers in order to get the correct style of fan. I don't recommend using adapters unless it's unavoidable.

Motherboard model should be printed directly on the motherboard somewhere. Usually along one edge or right down the middle.

My board is a Gigabyte GA-78LMT-USB3 Rev. 6. It's a starter board, not the best by FAR. I don't think I have enough fan headers on the board to fill those top slots, I'm thinking maybe buying a fan controller deck to put under my DVD drive. Those are usually SATA connections right? I have empty SATA connections on the board that are free.

Darkbreeze · Nov 14, 2017

Your board has only a single four pin CPU fan header and a single four pin sys fan header. You will definitely need some kind of controller or splitter board.

I highly recommend the NZXT Grid+. I use it in my system even though I don't strictly need to because it offers a bit better precision control of my fan curves than the motherboard controls offer. It also shows the fan curve visually using the CAM software so it's pretty dang easy to use.

Not terribly expensive either, although there ARE some less expensive options but again they don't offer very precise control and usually rely on the motherboard anyhow. Either will work and certainly be better than without though.

Just needs an internal USB connection to the motherboard and a free 4 pin Molex connector. On the V2 version anyhow.

About 25-26 bucks on Ebay: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR1.TRC0.A0.H0.Xgrid%2B+v2.TRS0&_nkw=grid%2B+v2&_sacat=0

Slightly more at about 32 bucks on Newegg and Amazon.

There is also a V3 version which has automatic noise detection and can adjust it's own fan curve to keep noise at a minimum based on several factors but that's a bit overboard here.

Another option that would work well might be one of these which would connect to your single four pin sys fan header and would supply power to each fan as well as fan signal, but would draw power through a SATA cable rather than like some of the four pin hubs that draw all their power through the single motherboard header which is too much for more than two fans to safely draw current through. This would be better and is less expensive than the NZXT controllers but would not allow as much fine tuning as it gives all fans the same speed based on whatever is set in the BIOS for the one motherboard header.
