Firstly im sorry if this has been discussed before, I did a quick search but was unable to find anything on this.

Basically I have bought a rig bundle from overclockers which came with an antec 1200 case. I want to alter the speed settings on the front 3 fans however I do not have the manual speed controllers.

How would I go about altering the speed of my fans?

Thanks in advance.
 
Yea I have the holes where the nob is meant to go and what looks like a cradle for where the switch is meant to be but im lacking the nob and the switch itself...

Ill have to have a root around inside and check if they have hidden it out of the way somewhere but if not where else can I change the speed?

Ive heard many people say about the 3 fans being loud but mine are very quiet so im assuming thats purely down to them being on a low speed. Id happily take more noise if my constant rebooting is due to overheating...
 
I bought the Tyrannosaur bundle and it doesn't say anywhere that they have replaced the stock fans...

I have just taken one of the fans out of the machine and there is definately no way I can alter it manually. The only wiring leading off from the fan is for the power connection.

Im confused.com!
 
Yea I just looked at the fan and it definately didn't have antec on it.

It was some other brand. I assume changing the speed of those said fans would be done via the BIOS or something.

Either way while I have been faffing around doing this the PC has restarted and bearing in mind my PC is directly below my window and has had the side off it for a while it definately isn't a heating issue.

Not sure what it is but its damn annoying...

Guess I don't need to turn the fan speed up though :P

Cheers for the feedback dude :)
 
My PSU is actually different to what is now displayed on that page.

I currently have a 1KW Silent Pro Gold PSU. I assume it is the same brand although I cant remember.

Either way because of the 1KW I figured it would be more than enough to run the 2 GTX 580's and that the reboots being a power failure due to overloading the PSU unlikely.

Hopefully I can resolve this soon because its been happening since I got the PC as stated which is coming onto 6 months now.
 
The PSU is a coolermaster btw...

The system reboots randomly only whilst gaming. It can be after 1 hour or it can be after half an hour or sometimes I can go for hours and not be affected.

Ive already sent it back to overclockers who replaced the motherboard for a newer revised edition but 2 days after having it back the restart happened again.

I then figured it might be something to do with a dodgy windows install so I formatted both hard drives and the system was fine for about a week and now im back to square 1.

Its really starting to bug me!

More on topic. I still don't know where or how to change the damn speed for the fans.

Oh and cleaning the filters is bloody annoying too :P
 
My latest reply from the OC staff was:

I would first try removing the bios battery and resetting the cmos to defaults.

My only issue with this is I have no idea what he is talking about...

Anyone able to shed some light on that?

I would send another webnote back asking for directions on it but the last time I did that I received a completely unrelated reply from someone entirely different.
 
Ive just sent them a new webnote asking for them to come and collect my PC and test it again as im not happy messing around with the hardware. Worst case scenario would be I do something wrong and void my warranty and basically throw 2 grand down the drain.

Cheers for the feedback so far guys hopefully ill get this sorted soon!
 
Well this is interesting...

I've set up a collection date for my PC and have managed to have EVE running for just about 12 hours now with no restarts, nothing.

One thing I have noticed is that when I check my card temperatures on Vtune it says the cards are around 40-45 degrees.

Normally during the crashes it would be around 70-75 degrees.

Does this have any relation?

Also is there a program I can use that will make logs of things like this so that when my PC DOES restart I can look back and see what it was that went wrong?
 
Whilst cleaning my filters on my front fans I double checked all of the wiring inside of my PC and a lot of it wasn't securely fastened properly. Since double checking every inlet/outlet and securing each connection as tightly as possible I have had no issues with rebooting including a 12+ hour stretch of running EVE.

Could this simple 'issue' have caused this problem to happen after all this time?
 
Well ive managed to use my PC for 3 days without any issues since making sure each connection is tightly fastened.

I really hope this was the issue.

I also feel a bit stupid for it! Oh well you live and learn!
 
Ive noticed my GPU's don't heat up half as much either. Even after gaming im still on around 45 degrees whereas before id be on 70+.

Im thinking of getting another fan for the side panel anyway.

Do you have any suggestions as to what I can use?

Ive heard outflow would be the better option but im completely clueless. If you could link a fan model that would be even better (from overlockers of course!).
 
Your better off with the side fan as a intake to help keep the gpus cool

Thats what I thought. They don't really have anything blowing on them at the moment.

Any idea what kind of fan im better off buying?

Preferably one overclockers stock as ill be buying from them anyway.
