Do I need more fans?

[joepa99]

Just purchased the Antec SX-835II with a 350 watt power supply. It comes with two rear fans installed. If I don't plan to overclock, is there any reason to purchase additional fans for the front intake? I plan to use the system for internet, video editing, and some gaming.

I would personally add one intake fan. I think it helps airflow through the case substantially.

I would, but that's just me. You are going to want intake fans to bring cooler air in.

My AXP 1800+ idles at 42, load 48 max nowadays and settles back down. After 14 hours, it still idles at 42 with the same load temps.

Before I had case fans (1 intake, 1 exhaust), Id hit high 40's idle and creep into the 50's with load. Just what happened in my situation.

Hey bro, while it's definately not necessary to drop in an intake fan, it may give you some peace of mind. My suggestion would be to get a good sized(80mm or larger), low db, low RPM fan to put up front. That should help your airflow enough, while not substantially increasing your noise level. Also, as long as you have a relatively well ventiated case front, the exhaust fans in your system should create enough difference in air pressure to suck in enough outside air to keep your processor cool enough to be rock solid stable at stock speeds.

Silence is peace of mind. The less fans the better. Very few people need more than 1 case fans, they just feel like they do.

You need an intake so your comp can suc as well as blo.

Cooler air coming in will reduce internal temps better than exhaust only, and the exhaust fans don't have to work so hard to bring air in if the case pressure is equalized with even one intake.

I have the exact same case and I replaced all the fans with Vantec Stealth 80mm fans. They're super quiet and case cooling is important when you have SCSI HDs.

I put two of these in the front of my SX1040IIB and taped the leads to the top of the case above the PSU.

If your computer is solid and doesn't crash randomly, then no.

Your points are true, but why do you need the intake? Unless you plan on running your system for more than 6 years, or are gonna do some fierce OCing, adding additional fans to an already rock-solid system is pointless.

Any time that the air flow inside the case is given a chance to breath well, it cools more efficiently that is better for all components inside of it. That includes the memory and chipset which can get quite hot even under everyday use and add on cards, sound and video. The hard drives also benefit and are usually the one component that people change the least in my experience. Also taking care of all the components equally, will improve the longevity of the system all together. You do not need alot of fans to do that, just efficient aspiration of the case. Personally I would move one of the stock fans to the intake and leave the higher of the two in place. Besides, there is no mention of having a rock solid system,only an empty case.

edit sp. and info.

Do you mean to tell me that two exhaust fans will be inadequate for normal system operation? I seriously question your reasoning teqwiz. Both AMD and Intel specify that a single exhaust fan, in concert with the processor HSF and PSU fan, is adequate for system cooling. Call me crazy, but I would imagine that these guys test systems for stability and longevity of hardware life. I am absolutely certain that this dude's system is gonna roll rock-solid without an intake fan, but even if it turns out that the system won't run solid he can easily increase his cooling as his stability dictates. You still haven't informed the rest of us as to why this guy requires additional fans in his system. So far your only argument is that you don't know what you're talking about. "Efficient aspiration of the case" is a loose ideal; maybe you could enlighten me as to how AMD, Intel, and Antec (remember, they designed this case for consumer use in the first place) all don't understand this concept. I am also currently typing this reply on an overclocked PIII 450 that has only ever received stock HSF/PSU cooling throughout its 4+ year lifespan.

P.S. about the edit sp. comment; I don't want to turn this into a grammer rodeo, but "Any time that the air flow inside the case is given a chance to breath well, it cools more efficiently that is better for all components inside of it." does not a sentence make. I may use net lingo a bit, but at least I can form complete thoughts

Eh, just ignore these guys, they are fighting uphill battles against themselves.

My recommendation, do whatever you wanna do, if you aren't tearing up your system, it doesn't matter. Try placing one in the front, one in the back, both in the back, in the different positions and all and see what kind of results you get.

Personally, I have my box set up with 4 Vantec Stealths, and a Antec TuePower PSU. The only thing I hear is my CPU fan. the 4 of these stealths are more quiet than any one generic fan.

The problem with stealths is that to keep silent, they don't move as fast, and therefore, don't move air as well. That's why I have 4.

So, after my rambling, I suggest either replacing all of your fans with stealths, or stick to your two fans and find the best way to fit them.

But then again, your system is still safe when your CPU is in the area of 65 C. Just make sure you keep an eye on it if your room starts to get warm.

good point ness, I'm gonna shut up now
