Hi All,

Got a brand new R9 290X today, I purchased a NZXT Enthusiast tower for it to go in as well as a Cooler Master G750M to provide plenty of power (got the case and PSU on a deal) but as I was just playing Battlefield 4 the PC shut down, like a safety trigger instant shut down. I took the side of the case off and straight away I could feel the heat that the side of the case got too before I even got in there, directly below the R9 290X is my power supply, I felt it and it's like really hot. I've tried HWMONITOR but I don't think that shows the PSU temperature, CPU cores look ok but then again they could have cooled down by now. Any ideas to diagnose it further, and if it does overheat the PSU what are my options?

yeah... your case is missing a lot of case fans... so the air is pretty stagnent. i see a stock fan on your cpu as well.

computers shut down like that when the cpu/psu/mb overheat. The gpu won't cause that type of shutdown... that said the GPU is probably loading that case up with hot air, and overheating something. First, lets establish it's an airflow issue.

keep the side of your case off, and stick a room fan in the openning. see if the problem comes back. if it does not, then it's a case airflow problem. and you're gonna have to start to add fans in there to move that hot air around.

I would check the temperatures on your graphics card first when you are playing BF4, since those are easier to check than the power supply temperature.

Good power supplies can exceed temperatures well past 100F or even 110F and be just fine. Of course, they like colder better but rarely do power supplies shut down because of heat.

Thanks Deemo13, I'll do that now as it would make a lot of sense. I mean if the metals heating up on the side of the case then that 290x must be seriously high in temps sitting in side the case with that hot air flowing around.

Thanks ingtar33 - I only got this computer yesterday and I intended on upgrading some of the components anyway. I'll do as you've stated and see how it goes, if it is a case of getting air circulating I'm struggling to think what would be the best approach. I mean looking at the position of the fan mounts it may be pretty useless, there's an intake fan on the front, and there's 3 areas where there's space for some fans. Two of them are on the bottom right (they align up with the hard drive cages, and one more on the back.) and finally one more at the rear. Do you think three fans could prevent this massive amount of heat from building up?

Many Thanks.

Reference R9 290X's got real hot anyway (95C). Make sure you've got latest driver to make sure fan runs OK in it (they did have problems). And a rear and front fans in your case of course. Some people were putting Accelero coolers on their 290X's to keep them cooler.

i7Baby - Thanks for the input mate, back to the cooling using a house fan. I quickly closed down BF4 as I noticed HWMonitor Pro states that my mainboard was at 118 Degree's Celsius, but it states the minimum was 118 and the maximum was 120 and now it's idling at 119 without anything running, surely this is a bug?

yeah... every little bit helps... you'd be amazed what a few good fans can do for a case.

Hi All,

So I had a little mooch around the rig and I noticed two problems which both really wouldn't have helped at all. First the front intake fan wasn't even working, after inspection I noticed the chap I purchased it off had cut through the wire and then used electrical tape. Wouldn't have been a bad job if there where more than three pieces of wire lol, moving further down the lead there was also a loose pin into the header, I assume this was caused at the same time the repair was carried out on the cut wire so definitely getting a new front fan. On top of the front intake fan not working, I also found out that the fan controller was set on the lowest, after sliding that up the difference in air being exhausted from the case was crazy good.

So I'm on the lookout for new fans now, any recommendations?

MSI Afterburner is a great software for adjusting the fan speed on graphics cards. You can also overclock on that software. It allows you to change the fan speed according to temperature, so the card can be quiet at idle and loud while gaming.

Hi,

I did check and yes it's 80+ Bronze Certified wshat ever that means? It was a fairly expensive PSU and has a single rail providing 62A to the +12v rail :)

Thank you Deemo, this is great to know. In terms of fan control does it offer any benefits over AMD's over clock utility? I'm only referring to the fan speeds more than the over clock

I personally think it does. AMD's utility can only manually or automatically adjust the fan speed. With the MSI Afterburner software, you can actually set a curve to change the fan speed according to temperature. For example, my 8600GT ramps up to like 50% fan speed at 60C and 80% at 72C. It is a gradual increase.

That's really good and was actually what I was looking for on AMD overdrive but I couldn't see the option to do what you stated. Having the lack of fans means I could really benefit from that utility by cranking up the fans before it reaches its optimal 95%. In saying that though since I increased the fan speed for just the two top NZXT fans it has been working an absolute treat! Especially considering I have no intake fan what so ever/
