evga gtx 1060 acx 2.0 single fan

We powered down the Acer machine with the EVGA GTX 1060 to install a second hard disk we recently received from NewEgg. The existing 2TB system disk was full and we installed a secondary 4TB hard disk to handle more games. We have accumulated a vast collection of games mostly from publishers who want their games reviewed by us.

We removed the video card to make it easier to install the hard disk, attach the SATA and power cables. After the hard disk was installed we reinstalled the video card. This approach is very conventional with µATX chassis which are harder to work with compared to a full tower.

We then plugged the machine back in and powered it up. Unfortunately the monitor did not respond with the BIOS menu. We tried a DisplayPort cable and it also did not work. We have 3 cables attached to the monitor for testing reasons.

We then opened the machine and looked at the fan on the GTX 1060 closely which was jerking off and on. Mostly the fan was off. This is not the usual way the fan on any video card should be working. We powered down the machine and waited a few minutes and the card still would not respond. We removed the GTX 1060 and checked the fan was not damaged. We also check the fan cable which was intact. So we reinstalled the video card and it again would not display.

Given the fan was not spinning up suggests a serious problem with the card. The fan is handled by a controller and a thermosensor. The fan on video cards will run at about 35% and then step up in speed when the temperature rises above a programmable threshold.

We take care to secure cables so that fans are not fouled which can prevent them from working leading to undesirable thermal problems. Modular cables make it less of a problem for cable management. Zip ties are a popular solution. We also check cards to be sure they are properly seated etc. We also check fan connectors to be sure they have not been inadvertently disconnected.

We then powered down and removed the EVGA GTX 1060 and installed the old GTX 750 which immediately worked properly. This shows the EVGA card has failed. We emailed support@evga.com and inquired about an RMA as the card is clearly not functioning.

Our Corsair AX860i at all times showed a green LED indicating power was good. So the PSU clearly is working as expected. The machine works fine now with the old GTX 750 installed. We still have a spare GT 630 if the GTX 750 ever fails which is why we are actively shopping for move video cards in addition to more storage.


We will be continuing to move installed games to the new 4 TB disk while we await EVGA for an RMA. The new disk should be able to cope but if it fills then we will look at getting another 4 TB disk. Seagate has larger capacity disks should they become necessary for the ever growing game library. 6 TB and 8 TB disks from the series are readily available. Larger capacity 10 TB, 12 TB and 14 TB disks use higher areal density platters which are more expensive.

We also discovered that Bethesda’s loader does not retain a users account credentials properly which is a problem. Nobody wants to have to enter credentials every time a machine has to be rebooted.


We posted this on the EVGA forum, it was deleted immediately. So much for customer service. We call it like it is which is the reason this site is so wildly popular. Their forum has become a real disservice for customers.
