Ordered my new rig but questions regarding fans for a CM690 PC case

Hi guys,

I've just ordered my new PC from NCIX and I discovered afterward that the stock fans (2x120mm and 1x80mm) that come with my case (Coolermaster CM690) might be a little bit noisier than I thought. Here's the rig I'm talking about :


Intel Core 2 Quad Q6600 Quad Core Processor LGA775 Kentsfield 2.40GHZ 1066FSB 8MB Retail Box

Gigabyte GA-P35-DS3L ATX LGA775 P35 1333FSB 1PCI-E16 3PCI-E1 3PCI SATA2 Sound GBLAN Motherboard

Coolermaster CM 690 Mid Tower Black ATX Case 5X5.25 5X3.5INT No PS Front USB Sound Firewire & eSATA

Western Digital SE16 500GB SATA2 7200RPM 16MB Cache 8.9MS NCQ Hard Drive OEM 3YR MFR Warranty

Corsair VX550W 550W ATX 12V 41A 24PIN ATX Power Supply Active PFC 120MM Fan *IR-$15*

Palit GeForce 8800GT Sonic 650MHZ 512MB 1.9GHZ DDR3 PCI-E 2XDVI-I HDCP HDTV Out Video Card

Noctua NH-U12P LGA775 AM2 Heatsink Heatpipe Cooler W/ NF-S12P 120MM Fan -12.6-19.8DBA

Crucial Ballistix PC2-6400 2GB 2X1GB DDR2-800 CL4-4-4-12 240PIN Dual Channel Memory Kit

Since I want to overclock but still have a somewhat "not too noisy" PC I wanna modify my order to get 4-5 of these instead :

I've heard only good things from these fans on many websites, what do you guys think ?

But my main concern is, will I be able to adjust the fan speed with a software such as speedfan or some other software ? (I don't know much about fans, as you can see). Or do I need to have fans with a temp sensor to be able to do that ?

Also, any opinions regarding the replacement of the side fan (80mm) would be appreciated. Which good but silent 80mm fan would you choose from ncix ??

Thanks !!!

Wow a lot like my system I just built.

Hmmm my case came with only 120mm fans. Thats odd yours came with an 80mm. I would use 120mm fans also on the side. They work awesome for my setup. The side panel supports them so definitely use them.

FYI, you can do awesome cable management in this case. I am very happy with it. I will post some pics when i get home from work tonight.

You guys are totally right, it comes with 3x120mm and not 2x120mm + 1x80mm (Even tought there's a 80mm fan slot on the side panel for the MB). (btw the case/PC is ordered but I haven't received it yet)

akhilles : Thanks for the thumbs up

WR2 : I've read on many forums that CM690 owners all think the stock fans s***k in this case (even if the case in itself is great). Not only do 90% of the owners think they're noisy, it seems they don't push that much air either


That's why most of them change them for yate loons since they're more efficient.
Don't worry about the price, I asked for a pricematch when I added the fans to my order, I did my homework and I knew they were cheaper on directcanada

Concerning the fan controller, I think I'll wait until I have the PC just to see how loud it is with all the fans at full speed. If it's too loud I might buy one, I'll see.

I just hope my modifications on my order will be processed before they build/ship my PC.
I ordered 7 of those fans !! Better have more than not enough

The airflow is definitely gonna be good lol

Thanks for the advices !
