Motherboard and GPU Purchase Advice Needed

Hi. I was planning to rebuild my gaming PC this summer. However, I have been getting a CPU cooling fan error message frequently when I start up my machine. For 3 years I have used an ASUS Maximus VI Hero motherboard with a Cooler Master Hyper 212 EVO CPU cooling fan. Physically the fan seems to be running fine. I ordered an identical replacement Cooler Master fan, and switched between the CPU Fan and CPU Opt plugs and still get the same error message. I spoke with ASUS and am taking their advice to try a different model cooling fan. I will give it a shot with the cooling fan that came with my Intel i5-4670K CPU. Even though they said that I should hook up the Intel cooling fan, take note of its rpms because they believe that the 600-650 rpm from the Cooler Master is too low, then manually adjust the rpms to a higher level on the Cooler Master, I see three problems. First, the motherboard BIOS does not have a manual rpm setting for the CPU fan, only max and min percent cycles. Second, I am not overclocking and prefer to keep the cooling fan running in auto mode to provide sufficient cooling at various temps. Third, the rep says the issue is more likely a BIOS problem. If this were a BIOS problem, why is it appearing within the last couple of weeks? I have not done a BIOS update in probably 18 months. I am starting to suspect that this problem may be a motherboard hardware issue. If I get this same error message after I switch to the Intel CPU fan, I am considering rebuilding the system immediately. The ASUS rep did not sound like he fully understood what he was doing. I just want to ask you guys if you think I am either dealing with a hardware or software issue.

The other question I have is regarding the GPU. I currently use an ASUS GTX 970 Strix video card. It is currently meeting most of my needs. I am trying to decide if I end up having to rebuild the PC now, should I upgrade to a GTX 1070 or 1080 or wait and see if Nvidia will release an update or successor this summer? If I remember correctly, there was a 2 year gap between the releases of the GTX 900 series and 1000 series GPUs. As I suspected, Nvidia would not provide any comment. As tempting as it may be to upgrade from the GTX 970 to a 1070 or 1080, I don't want to buy the card and find out shortly later that a new card is about to be released. Regardless of when I buy a replacement GPU, it will be done no later than the summer. Any advice on this issue? Thanks.

  1. Best answer
    Possibly a hardware failure. If the fan is running on the CPU cooler, there is little to be concerned with. It could be that the PWM feature of the CPU header is having problems? Which would only matter if you used a PWM fan or water cooling pump.

    Upgrading is always fun, but may not be needed if this is your only issue.

    As for the GPU, do you have a real burning need to upgrade right now? A new monitor with higher Res perhaps? If not, I would seriously wait to see what both Nvidia and AMD bring out this year. AMD is looking like it could bring out a real monster of a GPU at good prices, and Nvidia is sure to answer back with something as well, even if its just price cuts. All of this should happen before or by summer hopefully.
  2. Advice re: motherboard - get the newest/best MB/CPU combo you can afford. If you can get a Kaby Lake i7 and z170 mb, rock it! That GTX 970 should be fine for the next year or two and you will be able to upgrade the GPU to a GTX 1080 or whatever comes next, later.
