I have received the last of the parts I needed to build my daughters friends budget build but have hit a small snag. I was kindly given a Fenrir heatsink by Big Malc (thank you very much) but due to AMD's less than thought out mounting system I can only mount it with the fan blowing air from bottom to top. I have done this before with my families pc's but their cases have fans and vents in the roof whereas the Cooler master K280 case I have purchased doesn't. So how much will this affect cooling? PC specs are Asrock Motherboard, AMD 760K cpu (at stock), 4gb DDR3 1333mhz, 1TB WD blue, 460 Hawk gpu and an EVGA 500W psu.
I would build it and find out. Its not ideal but I'd say it would be ok. Graphics cards with blowers work this way do they not? Edit: I think blowers was the wrong word. I mean the graphics cards that dump heat into the case.
It's nothing a hole saw and 5 minutes can't fix Another approach if possible would be to get 2 very high cfm fans and mount 1 on the rear and one in the front 5.25 bays. Take the fan off the cpu heatsink and rely on the wind tunnel to provide the needed cooling. Approach works fine on servers. With the hawk gpu which dumps hot air inside, having the cpu heatsink blowing up, or rather pulling all the hot air dumped from the hawk into the cpu is really going to be very much less than ideal. At the very least you'll want a nice and powerful high cfm exhaust fan on the back.
For cooling at stock it's not an issue, it will still be better than a stock cooler and more than sufficient.
Well it's all fitted and windows is currently installing so we will see very soon what temps are like. I've fitted the Hawk in the lower pcie slot to give the cooler more space for air plus I've fitted a side intake fan in the side panel and an exhaust in the rear.
According to Asrock A tune the cpu is sitting at 40c with prime 95 loading all four cores. Seems pretty good. 55-60 FPS in skyrim, Ultra at 1440x900 (which is his monitors native) seems good as well, I hope he will be pleased.
I have the exact same issue as you have with my CiT Vantage gaming case whereby there are no vents in the roof of the chassis so the air is basically blown upwards in the case. As long as you have an exhaust located at the upper back of the case you will be fine. I've been running a 6 core AMD processor overclocked to 4.6GHz for a year now and I've had no problems!
I have do this a few times and no probs at all. Have a quick look at the pics HERE. I did how ever have the fans above supplying cool air.
Cool, nice looking case. You do have roof vents in that case which the K280 doesn't unfortunately but so far it doesn't seem to be an issue
Yeh I thought it should be higher than that, I've read that the 760k can be reading as far out as 20c but even then that's only 60c full load. Our house is pretty cold at the moment mind as the heating didn't come on til late.
Yup winter has some advantages. A great excuse to go on a gaming bender too (I'm just heating up the house!) Even if the temps are way out and it was a hot day and it was fully loaded it would still be absolutely great.
