GT 1450s or GT 1850s?

post #1 of 12
Thread Starter 
Hey all,

I am replacing the 3x Scythe Slipstreams on my radiator with 6x Gentle Typhoons.

I am cooling my 1090t and a single 5850 so i was thinking of going for 6x GT 1450's, thinking this would optimise performance and keep noise low (21dB each). Would this perform well enough or should i go for 1850s?

My only issue is that the 1850s are 7-8db louder each, and only provide an extra 7CFM of airflow.

I should also mention that the GT1850s are in incredibly short supply in the UK and are very hard to find, meaning I'll have to order fans and waterblock from 2 different sites and possibly have to pre-order, whereas I could order the 1450's and VGA block immediately.

What do people think?

I think that 1450's will cool well enough - don't get into trouble just for the 7CFM more.

I definitely think you should get the 1450's for lower noise

I've got both and generally find myself using the 1450's a lot more than the 1850's. You get a lot more noise from the 1850's, and you do get better cooling power but it never feels quite in proportion to the addition noise received. Given you'll have six of them running on a rad I'd got for 6x 1450's myself, without hesitation. They well do the job exceptionally and the noise will be entirely tolerable.

The 1850s are better, but you don't lose a lot going down 400rpm. Enjoy the fans and the silence

The AP-15's (1850 RPM) make a different kind of "hum" to the AP-14's. If I were you, and I am one to like my case silent, I would go with the AP-15's then turn them down to your liking with a fan controller.

AP-15's at 1450 RPM will sound better than AP-14's at 1450 RPM since they're not at full capacity. They will be quieter and sound a lot more pleasant.

If you have a controller, you can get the 1850 and under volt them. They don't make any strange noises like other fans, and work just fine in any speed.

I have 22 AP-15s in my system. Even at full force, they system is pretty silent, regarless of what people said to me that the combined sound will be too load.
I can also turn them down to 1200 RPM and they are completely silent.

Thanks for the help everyone, just letting you know i went for the 1450s, they came today and they're fantastic! People were right about them being a low hum rather than a whirr. I do have a fan controller, however, it only has 4 channels and i want rid of it, i dont want to have to fiddle around with them any more and want my case to look cool and clean as i have an 800D coming tomorrow.

Temps dropped by 15'c at max load to only 39'c (from 54). That should leave plenty of wiggle room when I add the 5850 waterblock tomorrow!
