[Official] Cooler Master ATCS 840 Owners Club - Page 43

post #421 of 4392
what up everyone

I just got my system fully set up. I took some picture to share with you all.
But I also have some question for you guys as well; hope someone can give me a hand.

I have a scythe mugen 2 heat sink for my i7 920 (overclocked to 3.6 and already lowered my vcore to 1.15) but it still idle at 50 and when i start gaming it usually go up to mid 60s. I already did the push- pull method for it and also added all the additional fans for airflow.


What I think the problem is:


1) I am using the intel DX58SO board and there is a northbridge heatsink that is located beside (that blue thing) the intake fan for my Heatsink. Can that heat affect my CPU temperature? Should I replace it with other chipset cooler? any suggestion?

2) Do you guys think that the noctua fan are not enough for the heat sink? or the airflow is not enough?

Additional info:
My room temperature is 35C , kind of hot this few days >_<.
and i am trying to built the most silent system as I can.


THANK!!!!!!!!!!!!!!!!!!

I have arrived at a total stalemate between the Cooler Master ACTS 840 Black and the Silverstone Fortress FT01-BW.

ACTS 840 Pros

-Size (great expandability)
-230mm fans are replaceable (stock fans are fine but I added this as a pro because the Fortress uses non-standard 180mm fans that are hard to replace)
-Beautiful (2nd best looking case I have seen)
-Additional fan mounts on HD bays and floor of case
-Dust filters effective and easy to remove/clean
-Nice looking aluminum interior. I prefer black interior but the interior of the ATCS looks better than a black one in this case.
-Removable motherboard tray

ACTS 840 Cons

-Size (cooling apparently suffers due to size, lots of dead air, and it takes up a TON of desk/floor space)
-I would have to go with watercooling (not because of the cooling, but because I will have all these fan mounts and space and I will be too tempted to use them )
-I would have to cut out my own window (CM window is ugly and not in the correct location IMO)
-Negative air pressure tends to draw dust in through the drive bays and expansion slots

Fortress Pros

-Size (nice and compact, doesn't take up a lot of space)
-Black interior and pre-installed window
-Good CPU cooling
-Positive air pressure reduces dust
-Even better looking than the ATCS 840 (this is probably the best looking case I have seen)

Fortress Cons

-Size (not much room for additional goodies)
-Dust filters are hard to remove and clean
-Intake fan is ineffective due to hard drive bays
-GPU temps suffer due to ineffective intake fan
-180mm fans are hard to replace, there are no other 180mm options
-No removable motherboard tray


AHHH! I am about to just flip a coin haha. The Fortress has more cons but it would save me alot of money due to not going with watercooling and I wouldn't have to modify my side panel. I wish CM would just save me some time by releasing a mini ACTS 840 and cut out a window that hides the drive bays!

You only get dead air if you are not using the right fans. The right fans should move the air around the case rather than have dead air sitting around. This is also not a problem if you do go water cooling anyway.
Negative air pressure problem can be alleviated by turning one of the top 230mm fans around so that it acts as an intake rather than as an exhaust. Just put a filter on it and no dust problems.

You can also remove the top 230mm fan closest to the front of the case instead, that did best for me. Both the FT01 and ATCS 840 have thin side panels. The FT01 is a tiny mid tower and the ATCS 840 is a huge full tower. Which one do you need? If you get the FT01 you can forget about water cooling.

@ J148

Thats really not too teribly hot to be honest. Still, its a bit on the warm end. Mine idles at 38-44, and full load is 68-77 on the cores. While I am gaming really heavy It can get in the high 50's low 60's. And i am OC'd to 3.8. Those noctuas are great fans, but higher CFM would definately help your temps drop. Like the CM R4's that a great deal of us are using. Fairly quiet and puch 90cfm, compared to your 55 cfm. Also, what TIM are you using? I dropped several degrees when i switched to OCZ freeze (my fav TIM).

As far as your NB HS affecting your CPU temps...i don't think it would have a very large impact on it to e honest. But ive never had a configuration like the intel board before, so i guess it is possible. Just not likely it would influence temps that much. Just my 2cents worrth here.

@ Keehar

Nope, using it just stock. I havent heard of a copper washer mod...please enlighten me. I can still move my HS back and forth fairly easily with my hand, so I know it could be tighter. And, therefore, cooler running. Im happy with my temps as of right now, but if this is a good mod i may give it a shot.

You can watercool the FT01 but it is a tight fit and you have to externally mount the radiator, which is better for temps anyway. The Fortress is probably a better fit for me but it has some design mistakes that are really kind of stupid like the filters not being removable and the front intake sucking, andthe CM ATCS 840 is just way too awesome to not fully consider. If I do get the ATCS 840 I will probably turn BOTH 230mm top fans into intakes and get some panty hose to make a filter haha. The size of the case is a bit of a con, but it isn't a major problem. I would prefer a more compact case but it isn't a deal breaker.

I've been thinking about doing it for a while because, as with you, my heatsink doesn't seem properly secure.

Adding a washer (not necessarily a copper one, stainless steel might be better), between the block and the retention bracket seems to solve this problem, and, in addition, adds more pressure onto the CPU from the block, which for many has resulted in a significant drop in both load and idle temps.

Slightly hesitant however. Not sure if the added pressure would damage the CPU. Perhaps going for a thin washer wouldn't hurt it. Anyway, you can read up about it here, though I would ignore the image on the first page, the washer on there is ridiculously large, I'd go for one about the size of that shown on page 5 (maybe smaller).

I do think that the TRUE is one of the best sir coolers you can get. I also believe it has the absolute WORST mounting system you can get of any cooler i have seen! Very difficult to get the fans on after it has been secured. I may in the future do the washer mod. But, after all i have done to the case, i really hate to redo it..lol
