I just realized while building my new rig that i put the back fan (120mm) backwards on my new system but i can't take it out cause i might mess up the rubber fan holders holding it in place (to reduce noise) but maybe i shouldn't worry since it is cooling only med end parts and i have a another 120mm fan in the front.
 
I dont think its funny at all, its your stuff, do what you want. However I suggest you turn the fan around immedately. If the "noise ripoff silencer" gets messed up, bolt the fan in and ....

The rubber gaskets can be bought from all over the place http://www.nexfan.com/40mmfans.html and I dont think they do much anyway.
 
Yeah a backwards fan can be very bad, but like you said if it all fries its no biggy. :rolleyes:
 
Cooling is one of the most important things when it comes to ensuring a long lifespan and performance of your parts. It is essential that it faces the right way. A decent 120mm fan blowing air down onto the CPU also cools memory, n'bridge, mofsets and anything else within reach. Worst case scenario is CPU failure. Best case scenario is you keep components going for a long time, can learn to overclock and get good performance.

The next most important (in my book) is a quality installation. I've had many people come to me with PC's more-or-less beyond repair due to shoddy installations. Things not screwed in properly because it was awkward to get in there is a typical one. DO THE JOB PROPERLY. Tidy your cables away at the end of the build. I assume you've got a fan at the bottom front of the case sucking cool air in? Keep the case tidy with cables tucked away and the cool air flows from the front bottom across the HDDs then mobo/CPU and out the top rear. Cables in the way block it.

On the same note, the cooler an electronic component , the higher the performance. Many people use water to cool their rig. Others keep temperatures way sub-zero. So...keep it cool....dude..... :D :D

Now that is what is funny, a vendor that is based on selling fans.

Can you actually make money out of selling fans and bits of rubber?
 
If they are the same kind that were in my Antec Sonata case, you just stretch them, and pull the fan off one rubber thing at a time. If you break them, they are like $3 to replace, or you can just use fanscrews.
 
I might meed fan screws but the reason i am not to worried is because the way they are blowing. See the fan i put backwards was the fan that took hot air out of the case while the front fan pushes it in (super lanboy case) but is the fan is backwards it is actually pushing in air so shouldn't it basically be cooling the top while the bottom fan cools the bottom of the case? heres a pic of it.:)

kind of the same pic but should know what i am saying.
 
It doesn't work well if all your fans are intakes. You need to bring cool air in the front and pump the hot air out the back.

take this guys advice.

this thread reminds me of when i thought my Cyrix 90mhz CPU didn't really need a heatsink cuz my 386 didn't need one... RIP Cyrix :(

Please CDdude take note of what I wrote in post #5 about a good quality build. I talked about cool airflow coming in the case front bottom, passing over your components and cooling them, then being exhausted as warm air out the top back. I mean it's you rig and your happy with it go for it but 'google' on airflow (posititve and negative pressures) and what the recommendations are and you'll see that this principal is sound.


Also, the fan at the top rear will be recycling warm air around the case. The air pressure will be higher in the case than outside so the intake will be less effective. There is barely nothing to take the warm air out.

We know what we talkin' 'bout dude...
 
That's not a bad idea but still nowhere near as good as the normal config cos warm air rises. Therefore that would leave more warm air sitting at the top reducing the life of the drives.



Anyways...an idea...this is how I learnt....

Try it with the current setup and monitor you CPU, mobo, GPU and case temps. 30 mins full load then allow to cool for one hour with no programs running and then check the idle temp.

Do the same test again with the rear fan exhausting the warm air out of the case and compare the temps.

That way you get a practical demonstration of good airflow and the difference it makes to temps and performance. ;)
 
I once installed my parents' exhaust fan backwards. I, at first, wondered why the CPU's temperatures were so low ... and why the hard drive died 2 months later. Poor airflow FTL. :(

I have since learned from my mistakes.

AMEN TO THAT. I am getting temperatures so low that some other guys on the forum are getting spooked by it :p But as I just keep telling them "meticulous workmanship" and "attention to detail" are the keys to success. There is no "easy solution" to having a very cold PC temperature it takes time, planning and a lot of thought. ;)

They do from me :D or did, for a long time they had the best price on Panaflow 120mmx38 fans but they havent been in stock in a while. Actually their prices are reasonable and have very good shipping and order processing times. ( I use a lot of fans /shrug so with the one price shipping for any size order they rocked)
 
I will take ur advice cozumel. i will also try and switch the fan around thanks to all the help!!:)
 
Well done dude. Take time to make it a quality build and you'll get so much fun and pride from your new rig.

Having everything tidy inside has another advantage besides cooling that I forgot about. It just makes it easier to maintain and/or upgrade components. If you've got wires all over the place blocking access then you gotta unplug things to get to other things. You've got a nice enclosure in the Lanboy (I do like Lian Li) so get the most of it and all your components.
