XSPC RX360 silent but effective help

the_real_7 · 09-19-2009, 04:01 PM

Ok make long story short I have a Black Ice GTX Xtreme 240 dual that used to cool my Q6600 and then I added a q9650 with that I also added to the loop a Single Black Ice GT Stealth 120 Radiator with these 3 YS Tech 120x38mm Fan - 126CFM , its very effective cools my 4870 x2 also loop never passes 31 c ...now I wanna drop this noise its like a jet plane all the time ! ! ! can you guys help me pick some fans to go with the XSPC RX360 so I can drop some pressure and i can drop this helicopter noise , im looking for around im guessing say 30 db max if not better dont know what cfm i need to make this setup work

Gentle Typhoon 1850s are my choice. They are OOS most everywhere, but sounds like they will get back in stock here in a month or 2.

Depending on the fan, most higher-speed fans will run on 5V - are the fans running off of a 4-pin molex? If so, you could switch the 12V wire on the fan plug to the 5V position, and see how the system runs that way. It'll definitely be quieter, and the temps may be better than you think.

MpG I tried the the higher-speed fans running mine at 6v and um damn they still like a hurricane 'and plus volted them down and they run terribly inefficient cause of the blade design ..... millertime359 Im hearing you on these Gentle Typhoon 1850s WILL THEY WORK , Hmmmm Im willing to try for sure , jab tec looks like they in stock

so should i hit the buy button

millertime359 · 09-19-2009, 06:56 PM

Yep, they should. Are the 14s or 15s? Last i check the 15s, 1850 RPMs are out of stock. Someon asked around and found out they should get brought back to stock in a month or so. I prefer the 1850s. Not loud at all and you can put on fan control if you want it keep it really quiet during non-gaming events.

If you can't source the 1850's (57CFM), the 1450's are almost equal airflow (50CFM) but notably quieter.

IMO the performance difference wouldn't be too notable

the_real_7 · 09-19-2009, 11:57 PM

hEY iandh and millertime359 if I cant get the 1850's should i go for the 1450's or something else Ive heard that radiator works really well wit low cfm , I would love the less db for sure , damn is this loud

millertime359 · 09-20-2009, 05:54 AM

The 1850s are not that much louder and a fan controller can tame them if they are too loud for you. iandh is right though, there isn't a huge difference between the 2 and if you don't want to wait the for a month or so to get the 1850s, then just get the 1450s.

I have the 1850s on the same rad. I put the fans on a fan controller and its fairly quiet. At least quieter than my san aces, but in a different way. If I turn the fans up to max, I can hear them, but I'm anal about noise. A fan controller is a good idea IMO.

IDK how noctuas compare to the 1850s though. That might be something to look into.

alacheesu · 09-20-2009, 07:34 AM

Are you really sure you need a new rad? I think I would try with just new fans first.

the_real_7 · 09-20-2009, 10:24 AM

Synthetickiller I think Im get the 1450's if your lowering the 1850's allready , well then the 1450's should put me in the sweet spot thanks guys for the suggestion
Also alacheesu I was going to try to keep my radiator but in needs monster cfm fans to work properly from my understanding cause of the tight fin design and also im running a separate 120 radiator to help with cooling

I know jabtech has those fans let me also check frozen cpu

It's not true that it NEEDS high rpm fans, it's just optimized for that range. It's perfectly possible to use low rpm fans on a GTX (or high RPM fans on the XSPC RX). Even though the XSPC RX would perform better with low RPM fans, it's not necessarily true that the GTX wouldn't provide sufficient cooling. Here's a chart from a review by Hesmelaugh that shows what I'm talking about:

With low RPM fans (400, 800) the GTX kinda sucks compared to the others, but at 1200 RPM and above the difference is small. You also see that you will lose performance when you move from the fans you have now to slower fans, no matter what rad you choose.

If you were buying a new radiator, or if you don't mind the cost and just want the best, I would definitely go for the XSPC instead, but in my opinion it's probably not worth the upgrade when you have decent rads already.

millertime359 · 09-20-2009, 11:50 AM

I leave my 1850s on full and can hear the pump over them. The 1450s will still be good for you.

The GTX's don't have to have high RPM fans, they just work better with them. If you have the money, I would switch out the the RX and either put those old rads up for sell, or keep for another build.

the_real_7 · 09-20-2009, 12:50 PM

Hey millertime359 just clicked the button at jab -tech got the XSPC RX360 and 3 x Scythe Gentle Typhoon 1450's sounds like it going to do the job just right on my setup dude , now one more thing how should I run my airflow this this time Push or Pull , with my old setup the pull effect work really good but my fan where high cfm so im not so sure it'll work the same again

millertime359 · 09-20-2009, 01:41 PM

Pull is better with low RPMS and push is better with high. There is a middle ground where those GTs pretty fall in where it doesn't really matter.

I hope it all works out for you
