I need airflow!

post #1 of 30

Thread Starter 
My CPU fans have been spinning relentlessly, and rightly so. I've got the most basic cooling system in my PC: stock CPU coolers, and stock case fans, with lots of optional fan brackets not in use. Upon further analysis, IMO, too much air is coming out, and not enough is travelling into the case.

The case is a Silverstone TJ10. My processors are AMD FX-74's, socket L.

Here's some pics of the inside and rear of my case:





A closer look at the top and bottom of the interior:





(yes, I know the floppy isn't plugged in...I don't need it right now.)

and the rear:





Here's a rudimentary illustration of how the airflow currently looks:




I have been looking around at aftermarket CPU coolers, but haven't decided whether a side-facing or a front-facing fan would best benefit the airflow.

Examples of two types of coolers I have been concentrating on are the Thermaltake CL-P0369 and the ZALMAN CNPS 9700 NT. If I got side-facing coolers, I don't know where I should point them. I was thinking of making them push the air towards the bottom of the case, making use of the vents at the top...Or, if I get the front-facing coolers, I could get two fans for the top vent to push air down to them. The mobo does have equipment to mount small fans on the three copper heat spreaders located above and below the CPUs, but they are meant to be used in conjunction with passive-cooled CPUs, so I didn't think it was a good idea to install them.

Though the case is set up for water cooling, I would prefer to stay with air cooling at this time, especially since I'm still new at DIY desktops. So, does anyone have some suggestions?

Nice setup!

How far are you willing to go in this?

The TJ10 is a very nice case - you just have to destroy it in order to replace the central fan (according to Silverstone's instructions...here).

What are CPU temps? OCing?

If you decide to start replacing/adding fans, remember the need to maintain slight positive presure. If you have a negative pressure issue right now, you will start to see the 'dust bunnies' begin their amass around the edges of your case and drive bays.

Let me know what you want to do - I can recommend some fannage, but it will have to start with the central fan .

I would say fill up some of those empty fan holes first (give me a moment to respond, I have to get to school and then post some more

Buck47: What do you suggest I do with the central fan? I see screws on the cover of the fan...But why would I remove it, since it is my only intake fan right now? Can you tell me what you have in mind?

The CPU temps are warm, but not hot--they are maxing at 57 under load, which is why the fans are staying on high most of the time. I don't OC anything (well, the video cards are factory OC'd, but that's it).

These are adjustable so you can have them face just about any direction and they can accept 2 fans...My thought would be to point them at the top outlets and add some slow rpm low noise fans across the board.
They also cool the under side of the mobo.

i was thinking along the lines of replacing all of your case fans to increase total airflow...easiest way to get more air through your case.

1 - higher CFM central fan
2 - lower cfm rear
3 - lower cfm top (if you decide to do a diff cpu cooler)

I wants them...But they're expensive.

Yeppo - so have you decided what you want to do?

Just because it would essentially be a repeat of what has already been said

For the time being, I think I would like to concentrate on the CPU fans, mostly because my finances are low right now and I cannot afford to replace/add too many fans all at once. If I get the ones RS has suggested, and direct them so that they are sucking air down into the case from the top vents, it will increase internal pressure, and directly cool the processors. Since they are adjustable I can always change things up when I decide to fill up all those empty fan brackets.

Thanks for your help so far, everyone. I am still 100% open to suggestions at this point.

A top of the line CPU HeatSink/Fan is going to cost about $50. Some of the cheaper ones actually do a reasonable job (even the arctic cooling ones which most people dis). First thing I'd do is get some more fans in the case and experiment with your airflow.

The YateLoons are good fans ... come in 3 different speeds, and can be adjusted with a controller or through the MB if you've got enough connectors. They are available here for $5 a piece.

And, if you go with a more expensive CPU HSF with a fan, you'll probably have the best luck orienting the fan to blow in the same direction as the nearest exit fan on the case (obvious, I know --- but I had to redo my first build because I missed this).

Good Luck, and let us know how things work out.

She speaks good werds. For 10 it doesn't sound too bank breaking to try and the fans can always be used elsewhere

I ended up getting some fans from the website Shazza (and GBQ) linked to. They should get here by next Tuesday. I'll let you guyz know how things go when I get them installed.
