first build fan speed question

Solution
Ok. Does the case fan have a 4 pin molex or a 3 pin connector. If it has a 3 pin, then you could plug it into your motherboard and it would run at the same speed as the radiator fan. If it is a 4 pin connector, either buy a fan with a 3 pin connector, or remove it. If the 2 fans are moving at different speeds and they are both on the radiator, I am pretty sure that one fan would strain the other.
What you plan to do for upgrading/overclocking seems fine to me. The thing is that case fans move the hot air out of your case, not move the heat from the heat sink. Large case fans are still good, but will probably only reduce temps by 1-5c.
What I was trying to tell you was that there is no need to have 2 fans on your 120 rad as it won't make...

There's seems to have been a hiccup with the mobile site. I did type out a long detailed post, then it asked me to write a description of the thread which turned out to be my first post. Where the other bit I typed has gone is beyond me!

So I'll start again.... Looong!

So, I'm almost at the point of putting together my first build. Aside from gaming this rig is going to be used for video editing, graphic design and some light 3d rendering. I don't plan on overclocking from the start, but I do intend to in a year or two. Also at the same time buying a second gpu to run in x-fire.

Here is the list of components:

Now. Pc partpicker doesn't have the antec h2o 650 I've got, on their system so ignore the fact it doesn't have a cooler.... Or monitor, I've got it covered...

My question. The antec case has a rear exhaust fan that I plan on using with the radiator and it's own fan for optimum cooling. Only thing is the cooler auto adjusts the rads fan speed depending on cpu temp. The case exhaust has a manual switch on the back panel for speed adjustment. The psu I've got also has fan controllers. What would be the optimal setup??

I'll be documenting the actual build once the rest of my parts arrive so if interested stay tuned on pcpartpicker.

It depends. If you want the fan to turn up as needed but turn down when not, use the cooler auto adjust. If you want it as cool as possible, use the case fan speed adjustment to keep the fan all the way up. If you want it quiet, use the case fan speed adjustment to turn the fans down. I would not use the psu fan controller.
I personally would use the case contoller and turn the fans all the way up because I want my pc as cool as possible and I where a headset so i would not hear the noise. If you want it quiet, again, use the case fan controller to turn the fan down.
Side note: Cool case. Never seen it before. Will probably use it on my next build.
Hope this helps :)

Also, if you are using a 240 radiator, I would recommend getting brackets to mount it externally. If it is a 120 it is fine. Also make sure your fans have 3 pin plugs or you can't use your fan controller and will need to plug it into molex plugs on your psu.
Good luck :)

Just to clarify...
The rear exhaust fan that comes with the case has its own control switch, that pops out the back of the case next to the fan.
The fan already attached to the radiator (which can't be removed) is auto controlled by the cpu copper heat spreader. I would want both fans to run in sync but am unsure how to do this. As I'd assume if they both run different speeds it might cause unnecessary strain on one of them. Any ideas??

I did not realize you said you had a antec h2o 650. In that case I would remove the case fan. It is easier to remove the case fan than to remove the fan on the radiator. There is really no good way to have the case fan run the same as your cooler's fan. Having 2 fans does not improve cooling anyway unless there is resistance in between them.
Also don't over clock your system. Having one 120 radiator and overclocking would defeat the purpose of water cooling it cause it would not be much different from air cooling. And definitely don't add anything else to the loop. Ussualy it is recommended to have 1 240 rad for cpu, and one seperate 120 for gpu.
Good Luck:)

Sorry what do you mean by resistance between the fans??

That antec cooler plugs straight into the mobo not the psu.


I can use the rear fan on the side window mount for extra gpu cooling and just have the radiator with the air duct leading to the exhaust grill. Have a proper look at the features of the components. The case has a massive top fan too!

When I'm ready to upgrade/overclock I can buy a secondary water cooler (240 as you recommended), use that for the cpu and mod my current cooler attaching it to the gpu. Would be a headache but I could do it.

Once again, Good Luck :)
