Push/Pull fans on a triple rad.

DavyBoy · 30 Nov 2009 at 19:27

Hi guys,

I was wondering if someone here could tell me whether I would see much if any difference if I were to fit another 3 fans onto the other side of my rad.

I remember when I fitted the 2nd fan onto my TRUE, my temps dropped by a few degrees, which I thought was really good, but would I be likely to see a similar drop in temps by using push/pull fans on a radiator?

Thanks in advance

No-one??

Sorry, I should have been more specific in the OP.

I'm currently using an Aqua Computer 360 rad, it's 45mm thick.

Fans that I am currently using is the Xigmatek XLF-F1253 1500rpm, attached directly to the rad, I would like to continue using these, as I really like them!!

However, in the new year, I plan to change my rad out for a thermochill PA120.4, and a 120.2, as I will be putting the mobo under water to, but that's a different story, all I really want to know is if I will see much if any benefits from fitting another 3 fans to my current rad..

atm my idle temps are around 36c, and under load running LinX they don't really go much higher than 60c, this is with my chip at 4GHz, and my GTX280 is also in the same loop.

I'm currently using a Laing DDC 10w that I modded to run at 18w, but what I had intended on doing was having my GPu and CPU in one loop on the quad rad, and then use a the 120.2 rad and buy another DDC with XSPC restop and put my mobo on its own loop.

I haven't fully decided how I am going to go about this, as I need to have a good think about it all, but in the mean time, I will get another 3 fans and stick them onto my current rad, as I want to push my chip a little further, however as it stands atm, when I try running it at 4.2GHz my temps go right up to 70c, as I have to give Vcore and Vtt quite a bump to get 4.2GHz stable.

I guess a quad rad for just my GPU and CPU is probably overkill, but I have been thinking about picking up a 2nd hand GTX280 for SLi, and I imagine that 2 x 280's and an overclocked i920 is going to put out quite a bit of heat!!

As for watercooling my RAM, I don't think I'll go down that route, as my RAM doesn't really get that hot tbh, although I really do like the look of the MIPS RAM waterblock for the Dominators!!

That's another thing that I have been trying to decide between, is whether I should go for the EK UD5 blocks or the MIPS blocks, I really like the look of both kits, but atm, I am leaning more towards the MIPS ones..

Which kit do you prefer out of these Jon?

Hi jon,

Like I said, I wasn't really sure how I was going to go about putting the mobo under water, I've only really started thinking how I am going to go about doing this.

You are probably right enough in that a 240 rad would be to much for just my mobo, so I will probably do as you have suggested, and have the GPU's on the 240 and everything else on the quad.

Regarding the mobo blocks, I really like both the EK and the MIPS blocks, but the reason that I am leaning more towards the MIPS ones is because of the placement of the ports.

One of the ports on the EK set looks like it would end up being awfully close to the top GPU, by the looks of things, in order to use a compression fitting in the port I'm referring to, you would need to use a 45 degree fitting, though without actually seeing the blocks I cant be sure.

Whereas with the MIPS blocks this isn't going to be an issue.

But at the same time, the price of the EK blocks is more appealing, as the MIPS set are really expensive!

My current fans are hooked up to my fan controller, and I usually have them running around 800 to 1000rpm.

Unfortunately I don't have any old/damaged 120mm fans lying around that I could use as shrouds.

Are you running your GPU and CPU in the same loop atm?

edit: an exception is one reservoir, two pumps where one drives the cpu block only and the other drives everything else. I think that's quite cunning, but it's not really multiple loops.

This was something else I was actually thinking about, I was looking into getting an EK multioption, and then splitting the tubing off using one of these Bitspower fittings, then routing the tubing off to both pumps that way, but I wasn't sure how well this would work out.

Like I said, there is still a lot of planning that I need to do first before I fully decide which route I'm going to go down, but I am sure with the help I get from you guys on here, I will find the best solution in the end!
