SLI 560ti HAWK Antec mod.

post #1 of 5
Thread Starter 
Just did "The Mod" on my SLI setup. My objectives/restrictions were:
- Reduce noise
- Don't get too much extra heat as a result of the reduced noise
- Had to do it in a 6 hours window (no kids, no wife)
- Couldn't get appropiate sandpaper, so no lapping
- Couldn't get MX2 so no removing IHS, this time

Here is how it looked before.

450

With this setup i was getting these temps: (with a 30ºC ambient temperature).
GPU1: 76ºC
MEM1: 99ºC
VRM1: 65ºC
GPU2: 69ºC
MEM2: 96ºC
VRM2: 64ºC

Initially, I was worried about MEM temps, which could take a hit after removing the original fan blowing over the stock heatsink. As you can see, I have a 12" fan blowing directly over the cards, and I thought that could help with the temps.

This is the spot where I plan to put both radiators. Despite having fan filters, there's a lot of dust in there
450

The first victim. You can see that I removed every single screw that I found under the card. It turned out that it's only necessary to remove the four screws surrounding the chip.

450

Here's the waterblock with the zip ties already there. I made another mistake here: attached the fan+radiator to the case BEFORE putting the block on the card. Nothing serious, but it made things difficult.

Another thing that made me doubt a little was the need to use only zip ties or use them with the AMD adapter that came with the 620s. To cut the adapter and make it fit, a special tool is needed, that I didn't have at hand.

450

This is the back of the first card:
450

And here is the first card installed. Since I was worried about MEM temperatures, I installed it at the bottom and tested this setup. Everything went well, so I proceded to mod the second/top card:

700

450

Front intake fan is now useless..

And both radiators on the bottom:
700

Don't have before/after Afterburner screenshots, but my temps changes after 1hr of BF3:
GPU1: -30ºC / MEM1: -2ºC / VRM1: +7ºC
GPU2: -18ºC / MEM2: +1ºC / VRM2: +8ºC

GPU2 is the bottom card in my setup, so it should get lower temps than the top card. So I must have done something wrong. This card was the first that I modded and I recall being a little careless with the block sitting (slided a little, because radiator was already screwed to the case). I'll fix this in a couple of weeks.

On a sidenote:
- Had to take a trip to the hardware store and get larger zip ties for the waterblock. Mine were a couple of inches short.
- Wasted an hour and a half reading about MSI HAWK weird temperature sensors. When tested the first modded card, MEM2 jumped from 46ºC to 77ºC and then to 95ºC, with no intermediate changes. I freaked out since the other card showed steady 65ºC. Shut down the computer and started digging the web. This is a common problem to HAWK cards, and probably it worked always the same on my cards, but I never payed much attention to these values. After a reboot, both of my cards acted the same (modded and stock), so I continued "working"
- After the mod, the pressure inside the case it's lower: removed to intakes (bottom and front) and replaced them with outtakes (both radiators).

To do:
- Change thermal compound
- Lap the waterblocks
- Maybe, change/add better fans (I'm thinking Noctua. Have a couple on the mail for my 920)
- Need to find sandpaper, MX2, metal cutting scissors, screws to put extra fans for a push/pull config.

Bottom line:
I'm very satisfied with this mod. Every little bit of less noise helps. And it's very easy to do. Tubes fitted well inside my case, despite being midtower (CM690). MEM and VRM temps are reasonable, and the only "extra" that I put on them was increasing the side fan RPM to the "max" (about 1100RPM). It seems to me that having less hot air inside the case (HAWKs don't expel the hot air) is making everything else run cooler: my 920 is reporting a 4ºC reduction while idling.

Nice man! I suggest some good thermal paste like Mx-2 or Mx-4. It'll def help!!!!! I'd get a case fan on those VRM's too!
post #4 of 5
Great write up, good read. I used Mx4 for mine and ac5 the first time I did it. Do have air blowing on the card, it helps. Glad you liked the Mod, our little group is growing quickly

Well done! It took me a couple attempts to get both my temps inline with each other. I was running about +8 on the bottom card. Was due to a poor seat with a pretty huge air pocket. doh.gif
