Oh yeah, I forgot to mention, the Antec formula 7 is very thick, i would heat up the tube with a hair dryer or running hot water.

Thanks for the hheads up I sure wouldn't have known to prep the therm. paste. I'm wondering now, though If that trick would have worked with the Zalman paste that came with my 9900 max cooler that's on my Fatality Scorpious rig. That cooler was high quality but the black paste was like 10 yr old toothpaste. Thx again I'll post pics of the Antec install 2mor eve. BTW , check this out below-- Ihad to order one for the future cuz at that price, a 240mm is 2 good 2 pass up!

I've used Zalman STG-2, it's pretty thick but not as thick as formula 7. Actually I forgot, that STG-2 performed really well for me. I used a CNPS9900MAX for a while, good cooler...

Yesterday I started building a new gaming system, and installed the H2O 620 in it. When tightening the screws, there is a point where the screw will spin indefinitely. I searched through this thread, and saw some similar issues described, but in those cases the metal insert/receiver was deforming the plastic bracket etc. I can confirm this is not the case with my setup, the metal insert is still fully inserted in the back plate. Is this normal? Are these new thumbscrews Antec came up with? I believe this is a new version of the H2O 620 (with LGA2011 support etc).

The waterblock doesn't budge, so it appears to be installed correctly. Also, all four screws have the same issue, so I can't imagine they're all stripped somehow. I don't really have to tighten them that much for them to reach the 'free spinning' state.

Thanks.

Yes this is common, if you overtighten the thumb screws it strips the plastic backplate. It looks like the metal pegs are still in there, and they are, but they have a little metal lip on them and they have dug into the plastic backplate and it lets them spin as you turn them, endlessly. The screws are tight enough, in fact the tightest they could get was right before they started digging into the plastic and spinning. The only problem you may have now is the removal of the coldplate/pump is you ever need to do so. My backplate is stripped too, to remove it I have to take off both sides of my case, use a screw driver one side and a pair of needlenose pliers on the backplate side. If you press in hard with the screw driver the peg will stick out of the backplate enough for you to get a hold of them with the pliers. Then you can unscrew them. I wish they would make a sturdier backplate though....

Did Prime95 heat and power consumptition test on my system today and the results is amazing! biggrin.gif

I've removed the stock cooling paste(s) on both my Antec 620 and my AMD FX-8120 CPU with chemical petrol, very effective! And applied new cooling paste, the Arctic Silver 5 thumb.gif
Installed a second fan on the 620 rad and mounted with a second set of screws that i ordered, currently using the NZXT fan that came with my chassi as the second one and it is mounted in push N pull as exhaust (hot air blows out from my case) smile.gif
Latest part that I installed is the Bitfenix Spectre PRO 200mm (black without LED's) in top next to my NZXT stock 200mm, both as intake of cooler air!

Going to change both 620 rad fans to Scythe Gentle Typhoon 1850RPM in the same PnP configuration! biggrin.gif
Going to replace the rest 120mm case fans to Be Quiet! Shadow Wings 2200rpm(!) to get maximum airflow smile.gif

So far my temps using Prime95 as burntest gone from 72 degrees celsius on CPU to 56 degrees using heat test in prime95 for 15 minutes! And the core temps gone from around 56-57 degrees to 40-41 degrees, amazing difference! I'm more than happy with all my parts and the cooling is great! specool.gif

Pic of the temperatures recorded today!

Nice temps!

But how many of your case fans are intake and how many are exhaust. I typically get the best results when I have slightly more exhaust than intake.

Thanks biggrin.gif
Antec 620 Push N Pull as exhaust in the back, dual 200mm fans in top as intake, dual 120mm fans in the side as intake and the 120/140mm front fan is going to be mounted as intake smile.gif

Yikes! That is a lot of intake. Getting cool air into the case is good thing, but it is more important to get the hot air out of the case, as most of your components produce heat. There are pros and cons to both negative and positive pressure air cooling. However, negative pressure cooling (more exhaust than intake) keeps the system temperatures lower.
Quote:
the next decision for you to make will be between positive and negative pressure. What I mean by this is that there are different benefits and drawbacks to be had depending on whether there is more airflow into a case or more airflow out of a case. With a positive-pressure system (and filtered fans), the inside of your case will stay cleaner because the only air entering the case will be filtered and the extra air that isn’t exhausted by the exhaust fans will blow out through cracks and vents in the case. With a negative pressure system, the vacuum inside the case will pull air in through those same cracks and vents. A negative pressure design, however, will result in better cooling because it keeps a constant stream of air moving through the case at all times.
-Xoxide

With a high end case like yours almost all of the air being pushed into the machine will be filtered. You would have better results with a standard setup of top and rear exhaust with front and side intake. Hot air has the tendency to expand and rise, cool air settles toward the bottom naturally. That is why most cases are designed for top exhaust and bottom intake.
