There would definitely be contact between the fan clips and the 7970 on its way and so I repositioned the cooler and its fans to what is shown in the pictures as it gives more space for graphic card. My questions are;
1) Will cooling performance take a hit with this position of cooler and fans? (Case is an antec 900) I ask because I'm unsure if I should be impressed with the cooling performance of this cooler combined with my chip (3570K @ 4.5 GHz / 1.310 V) as I'm seeing average 100% load temperatures during Prime95 of low-mid 70's with peak temperatures in the low 80's.
2) If there is contact whatsoever between backplate of card and cooler, what should I use to insulate? I'm thinking I will slap on rubber tape or maybe electrical tape in areas where there is contact... ?? ...
No matter the position, it seems it is going to be tight fit regardless... I'm thinking how the heck am I going to remove the graphic card for future GPU upgrade... Should I just return the Noctua NH-D14 and grab the H80 or Antec 920?
Yes, that position is bad.
You should turn that so that the fans are sucking from the front and blowing out the back. It WILL give you slightly more clearance from the fins that way as well, but the fan brackets may stick out a little, just stick electrical tape or something else in between them to gaurantee they don't make contact. There is a post about this in the TJ08E section of this forum (talking about the clearance of NH-D14 and Silver arrow). You can also I think bend the clips a little to help with clearance.
By default the noctua fan is pulling air IN to the heatsink, so you would have that fan closest to the front of the 900 to get the air from the 2 front 120mm Fans. Then the rear 120mm fan also acts as an exhaust for your heatsink. By far the ideal setup for the Noctua in an Antec 900 (I've had 2 900's and had noctua's in both)
The way you have it pictured is either blowing the hot air on to your video card (if you have it blowing through like the noctua does by default) and fighting with your top exhaust fan (bad flow) OR you changed the fans around and have it sucking the hot air off your GPU through your heatsink. Either way, not a very smart idea.
Other than a custom water loop you are not going to get much (really any) better than a Noctua NH-D14. You MIGHT see 1-2c with a Phantek if you believe that, I don't. You MIGHT see 1-2c with an H100 with really annoying fans. Again not worth it. H80 is a downgrade in cooling from an NH-D14 (both performance and noise). As is the Antec 920. If you think your unhappy with the Noctua's results wait until you spend the money for one of those and see the results.
Changing your layout will help, but Ivy runs hot, nothing you can do about it.Edited by crawlgsx - 7/5/12 at 7:22pm
