900D Build Log - Green and Black watercooled.

Alphacool UT60s are pretty good. So are XSPC RX series.

As for the UV, don't bother. UV lighting doesn't really work unless the room is completely dark, and you have no other lighting in your case. Even LED fans can spoil it.

I wouldn't have bought the 2600k though tbh. That price isn't exactly outstanding, and 2600ks are just 2700ks that couldn't reach good overclocks by the end of Sandy.

I was recently looking that the Alpha cools. And fair enough on the UV opinion. I have to argue though against the 2600k it has brilliant overclocking potential and the difference between them and 2700ks are literally 0.1mhz and maybe a bit more overclocking room! Plus I got mine for a very good price. When you compare a 2600k to anything higher price wise it doesn't make a credulous amount of sense price/power wise!
 
The 2600ks came out first, then with improvements to it, the 2700k followed as it could reach higher clocks.

Then as Sandybridge progressed, it stopped being worth making the standard 2600k, and so Intel only really produced 2700ks. The bad batches that were unable to reach the high overclocks were taken down the 0.1mhz and rebranded as 2600ks.

Therefore, any new 2600k you buy today is just from a bad batch of 2700ks, and so won't overclock as well as the proper 2700ks.
Not saying there's really that much against buying one if you can find a decent price as the arch is still great... But it's a little off-putting that you know you haven't got a good clocking chip before it even arrives.

£205 isn't exactly a great price for one either. When Ivy first came out, they went down to around the £200 mark. They've only gone up again recently as supply has decreased.

You can pick up a 3770k for only £240, so you'd have been better off with that.

when was this? I bought it a good 6 months ago?
 
It was well over a year ago when this started happening.
You may have got lucky and got an older unit though I suppose - depending on where you got it from.

It's not really a major concern. Like, I doubt I'd replace it if it were me. I'm just saying don't expect massive overclocks

Well I'll practise my rain dance and hope the silicon lottery favours me XD
But I appreciate the knowledge!
 
More questions

Can someone tell me what I should do to control my total of 4 fans at the bottom and 6 fans at the top all 120mms? What Cables or power splitters I'll need? That would be awesome :)
 
I use these:
http://www.overclockers.co.uk/showproduct.php?prodid=CM-108-BX

Well, don't really use them anymore as I've got the fan hub that came with my Switch 810, but I would be using those without that.

With a pair of tweezers you can easily rewire it to 7v or 12v if you want to change it.

No need to be controlling fans depending on your task though, so no fan controller. Just get those and leave them be.

:)
you my friend have been nothing but awesome! Could you give me a quick run down on what you mean rewire it?

Not to hijack your question here or anything, but I think I know what he means. See how there's only 2 wires going into the molex plug? if you put all 4 wires in, it would be running at 12v, and I'm assuming 3 wires means 7v. Not entirely sure. Just fill in the other 2 wire/pin spots, distribute all the wires evenly to the 3 fan headers, and job's-a-good-un. (I swear I've been hanging around these forums/Tom's YT channel too much. I'm starting to use UK slang :lol:)

are you sure? I just looked at the 7 v version and all the cables have done is move to the 4th slot. I can't see the other "4 wires" XD Maybe I'm derping seriously hard. GOOD UK slang is the best until you start to talk like a chav. :lol:

Derp. :banghead:

I see it now. The only difference I can see is where the 2 molex wires are plugged in. I'm not the savviest on electronics/wiring, so I'll let James give you a definitive answer, haha.

Also I meant to say 4 pins, as in the 4 pins on the molex connector.

It's 1:49 here. The house is silent. Apart from that fact I just laughed so hard at the derp animation, waking up everyone.

Sorry, that's not right :)

A molex plus has 4 wires:
12v, Ground, Ground, 5v.

You only need 2 wires for fans so can either run it:
12v and ground - to give 12v.
5v and ground - to give 5v
and
12v and 5v - which together (somehow) gives you 7v/-7v(?)

So basically, you have 3 choices as to what fan speed you want to set up.

So if you buy the 5v one, you can get a pair of tweezers and move the plug from where it's at at Ground, to the 12v position, and you'll get 7v through to the fan.

Ahh, okay. Maybe the 12v or 5v cancels one out, so 12-5=7, or 5-12= -7? Like I said I don't know much, so I'll take your word on it lol.

Heh, yeah it definitely is that. I have no idea how it works either tbh though.

Definitely beats wiring around fan controllers though.
 
Just wanted to let you guys know i found that fan voltage tweak tip very useful - thanks :) But u sure this works JR94 - tried it yourself?

Yeah it does work... And I do use it myself.

I have a molex fan hub that I have 2 modded molex extenders for... One being 5v, the other 7v.
I just switch between them if temps ever become a problem.

I used to use the Bitfenix ones that I linked - again, just rewired the end until I found the right balance between noise and temps.

There are a few threads about it on here:

Very cool :D Thanks for the tip & link. May come in handy at a later stage - for now im just using the native controller on the R4.
