What I suggested is only about twice as much reading as your original post.

I honestly don't care if you read it or not. But I'm not going to waste my time trying to help when you are not motivated enough to help yourself. mad.gif

Hahahaha I wish I was giving excuses man. I appreciate your help and hope you keep helping me, but believe me when you have to work 10+ hours a day ( frown.gif ), you just go home, eat and sleep.


Anyway, into what concerns us. I read your post, pretty detailed and you taught me a few things thumb.gif

So, based on your post, for this case I think you would suggest that I control the single fan (on top of the CPU) with a PWM connection from the board and the two other fans in the GPU area with the Mini-4Pin GPU PWM cable splitter. The webpage for my board (ASROCK Z87E-ITX) doesn't says explicitly if the two fan headers are PWM, although they both have 4 pin connection, so I will assume they both are. The only related description in their website says:

- CPU/Chassis Quiet Fan (Allow Chassis Fan Speed Auto-Adjust by CPU Temperature)
- CPU/Chassis Fan Multi-Speed Control


I have decided to not consider LED fans because I often leave the computer on while I sleep, so they would bother a little. All I need now is to get three good fans and set them up with PWM.
Which ones would you recommend? The ones I put in the first post are the ones I've annotated because of either lots of good reviews or they are mentioned a lot.

If you would also suggest that I change the Intel stock cooler for better temperatures, the CPU height limitation in the case is 83mm after removing the case fan.

Thanks again for your help, I really appreciate it biggrin.gif

Jetflo's are garbage, bought 2 recently and returned them. Way too noisy for 2000rpm, sounds more like 46dBA than their listed 36dBA. Replaced with 2x Cougar CF-V12HP PWM.


Thanks for the suggestion, will check out those fans as well thumb.gif

I've been trumpeting the importance of firmware-based fan speed controls for what seems like an eternity, and perhaps someone at ASRock has been listening. The Z87E-ITX's fan speed controls are the best I've seen incorporated into motherboard firmware.

The CPU and system fan each offer multiple presets in addition to a configurable profile—nothing we haven't seen already. What's new here is the degree of control over the custom profiles. Most motherboards let users adjust the high and low fan speed and temperature thresholds for custom profiles. On the Z87E-ITX, temperature and speed values can be set for four points along the fan profile. Make that 4.5 points; users also have control over the "critical" temperature at which the fan kicks up to full speed. The profile's minimum speed can be dropped to 0%, too, allowing the fans to spin down completely if temperatures are sufficiently low. To my knowledge, this is the first time such granular fan controls have been available outside a Windows-based utility.

Unlike the Windows-based software we've used, the firmware's fan profiles can't be manipulated by dragging points with the mouse. The values for each point are entered manually, and the illustration in the sidebar doesn't reflect your settings. At least the values available for each point change to ensure that the curve maintains an upward trajectory. The foundation is excellent, but the interface could use some work.

What kind of temps are you getting now? How much noise does stock cooler make? I believe RVZ01has 83mm CPU clearance. I'm using a Thermalright AXP-100 cooler on i7 920 with no problems. Very nice little cooler and 58mm with fan in RVZ01 83mm a 15mm thick case fan would fit.

I did a mini-review here

Here are drawings of your motherboard with measurements. Second and third images are motherboard measurements. Height of RAM is also critical for cooler fit.

Edit: What is the clearance between vent and video card?

Wow excellent! I'm lucky I picked the board for other excellent features and also has great fan control in the firmware as well.

Stock cooler is noisy up from 75% load and up (65c temps and up). I picked low profile RAM so that should not be a problem. The stock case fans are quiet but they are not PWM controlled right now, the cable extender the case brought is not PWM capable.

The total space in the graphics card area is 68mm. Almost quoting the manual, with a dual slot card, a clearance of about 32mm would be left for fans.

Edit: CPU temps at idle are between 36-40c. Playing games goes up to 55-60c. With a Prime95 test it goes to 80c.

So system is okay as is. Better cooling will mean it runs quieter too.
You case is a real challenge because it is so different from anything I've worked with in the past.
We don't want intake fans too close to CPU cooler or GPU cooler fans as this increases noise.

GPU vents will need to be intake as that's the only way to supply air to GPU.
CPU vent can either be intake or exhaust. Probably test to see which works best.

If we use the vent above CPU as intake / exhaust where will the side vents be enough area? I believe so.
With 2x intakes in GPU vents will the other side be enough? Not sure it is.

When you say the system is okay as it is, do you mean I should use the stock fans and connect them to PWM cables? Or you refer to the rest of the setup (RAM, etc)?

In your last statement I think you are saying that the cool air from the gpu fans reaches the cpu area. I'm not so sure about that since the adapter to mount the GPU covers a great area. Only in the middle is a small opening big enough for some air to pass.

I mean system is cooling at reasonable temps. If the fans you have now are PWM fans by all means get a PWM splitter and use them. The PWM splitter will be needed to control eplacement fans anyway.

No, I mean 2x fans / vents by GPU supply air to GPU. Fan / vent above CPU supplies CPU.

I'm not sure if they are but I will check that out. They were introduced with the case and are not sold individually so I'll check if they are already listed on Silverstone's website or the fans itself have the info.

I'll be ordering the PWM splitter, test the CPU slim fan as intake and exhaust to see which works better and verify new temps on GPU when I replace fans.

It's better to go with GPU PWM on the GPU area right? They will be supplying air mainly to the GPU anyway.

it is easy to tell if fans are PWM or not. 4 wire plug is PWM, 3 wire is voltage control.
In your case yes, Fans supplying air to GPU will do better job with GPU control.

Just checked them out, they are not PWM.

I was reading this review on the AXP-200 http://www.tomshardware.com/reviews/low-profile-heat-sink-mini-itx,3639-12.html

Would it be better than the AXP-100? They recommend noctua and zalman there as well, but the Noctua I would have to use it with the 92mm fan only. The zalman should fit though.

Was reading for case fans as well, The Noiseblocker M12-PS and Scythe GT caught my attention. Noctua as well although I think they are a little pricy. What would you suggest?
