From the beast to a beauty (hopefully)

So today the last piece of the jigsaw arrived. Must say looking at it in person i dont see where they get off charging £25 for this rather small piece of metal lol.

I guess at least part of the issue is if you use the 9x120mm fan mount you have a better chance of buying £100 worth of phobyia fans as opposed to £40 worth with the 180s lol.

So I fitted the fans to the rad, yes, they are held in place by cable ties, i didn't trust the screws that came with the rad not to put some nice holes in it

Ok so time for some testing results

What I did was run prime 95 and furmark at the same time, leave the system for 30 minutes then take a screenshot of HW monitor

First up, with all the fans turned up to full

Pretty impressive temps IMO, with an ambient temp of 23C that gives us delta temps of 48 on the hottest CPU core and 23(!) on the GPU

Next up i put all the fans on the lowest they would go, to do this i turned them off and then ramped up the percentage in speedfan until the fans started spinning again. So its the minimum power needed to start the fans not keep them spinning.

Again not bad, with an ambient temp of 22 we get a delta of 53 on the hottest CPU core and 26 on the GPU.

Next i ran the rad totally passively, all fans turned off

With an ambient temp of 23 this gives us delta temps of 71 on the hottest CPU core and 47 on the GPU.

Running passively this was probably a bit hotter than I would have liked, but really no application is ever going to be this stressful on the system.

One thing that might be worth noting is that i had to do 2 passive tests on the first time after 20 minutes or so i had a random shutdown, not sure if it was related to heat or not though.

All in all i'm very very impressed

Some good results there dude

Your passive temps for normal use in your previous post are pretty much what you would get on air.

Personally, for normal use, i'd run the rad passive and then when things get a bit toasty turn the fans up a bit.

That's some very nice results, very nice radiator

So you have the 4x 180mm fans connected to the motherboard?

Did you use 3pin female to 4x 3 pin male cable to have them all to one 3 pin on motherboard?

When running the fan's at lowest is that gaming or some heavy benching?

Also did you let the temperatures stabilize or just run for 20mins?

I think the best thing is to run until temperatures stable, also be careful on cpu temps, I'm no expert on Intel cpu's but I would personaly want below 70c on Intel?

yeah all 4 fans running off 1 mobo header using a splitter

all tests were run by running prime95 and furmark burn in test together, so maxing out both the GPU and the CPU.

Generally with my CPU i try and keep it below 90, back when i was first overclocking it ran in the mid 90s for a while with no ill effect

Thats pretty much what i've done, i've set speedfan to keep the fans off up until about 67c then it slowly ramps them up to full as it approaches 80

That's interesting did not know you could turn on fans this way from poweroff mode.

So once any temperature hits 67c the fans turn on from being passive turned down?

How many fans do you have inside the case for airflow?

 

[jonnyfgm]

yeah when the temp hits 67 the fans go from 0% to 45%, then slowly ramp up.

inside the case I have 2 120mm fans (one noctua and one bitpheonix) which run at max (well the noctua with a low noise adaptor) all the time, then 2 140mm fans which are wired up to a fan controller along with the LED strips

I dont think the fans are really neccessary most of the time but the PC wont boot without a fan plugged into the CPU fan header
