You would need to be writing over 15 gb's a day average for it to be problematic within it's lifetime.

The majority of users will never be writing this much data.

Not the best choice for video editors but for the majority of people TLC nand is fine.

That was my point. For what is supposedly one of the worst endurance drives out there, it can write a ****tonne of data, to the point that for 99% of people, they'll have replaced the drive with some new breakthrough technology before it becomes an issue.

My 32GB Onyx is at 90%, and that's after being an OS drive for three separate machines, and it's been over three years since I've bought it.

This looks amzing..

Can somebody explain why some GPUs are able to sustain "higher" 9I put this in quotation marks because I think this might not ultimately be the case, I explain what I mean below) voltages with potentially worse cooling.

For example, I here people of having 1.2-1.3v for their 7950s. I cannot sustain over 1.1v on my Dualx cooling. The GPU temps are just about manageable, but the VRM temps go a bit out of control at that voltage (something which might change when I install more than my single current case fan).

As i understand it, high ASIC-scoring chips need less voltage to sustain higher overclocks. This seems to be the case with my card. But it does not explain why other cards can sustain similar speeds (say 1100-1150 mhz, even 1200mhz) on much higher voltages. Do these cards have much higher voltage drops meaning that the heat is dissipated in the circuitry more "evenly" meaning setting the voltage to higher is necessary?

My card cannot sustain even stock clock speeds at 1.2v, and I hear of other people needing that kind of voltage to overclock.

Thanks!

I'd imagine your case airflow is the main issue. 1 case fan is not going to provide good airflow. For example I have 2 x 200mm intakes and a 200mm and 140mm exhaust in mine. This could lower temps by over 10c compared to yours. There's other factors like small differences in manufacturing and the quality of the gpu itself.

My card isn't the may west. I've had it clocked stable as high as 1200 on the core but I needed 1.275v for this to be stable. However under heavy loads it got pretty loud. I'm back down to 1100 on the core with 1.2v which is still high for that clock but noise levels stay below what I can bear.

I was half thinking of getting a new cpu lads. Thought i treat myself at the expense of bet365 but been reading up that there's probably no point upgrading from the Intel Core i5-2500K

You don't need a new cpu. I wouldn't even bother going to Haswell. Wait for the next tick or tock after Haswell. Either Broadwell or Skylake.

It's also a Sapphire dual-x but its's a 7970. I have a fairly relaxed fan profile up to 70c at 55% where it ramps up quickly past this point.

It stays below this at 1100/ 1.2v. It was going past this and ramping up at the higher speed and voltage.

It might explain why I need a bit more voltage but temp wise there shouldn't be much difference at the same settings.

One of the 200mm is a side fan blowing directly on the card which I'm sure helps quite a bit.

There may be but at the moment you have 1 case fan.

Improving case airflow should improve your gpu temps by 10-20c.

Really? OK, Cool. Sher I'll see what it's like when I get some fans.

Scratch that, they don't ship to Ireland. I think I'll get the Arctic F12s (pity they're a lot more expensive on Amazon). Do 3 pin fan headers not provide ANY fan control? I've read in a lot of places that the F12s move a lot of air but are extremely loud at maximum speed.

parcel motel?

Never used them actually.

I think I've changed my mind, though. I'll go the for Arctic F12s. The reviews vary from "amazing for the price" to "f*cking awfully loud" and the reason for it is those who are complaining are letting the fans run full blast, when the fan pushes more than enough air when not running full blast.

There is fan control through 3 pin headers, right? or no?

You can change the fan speed through the BIOS or mainboard software in windows if they are connected to the boards 3 or 4 pin connections.

The F12's are loud at full speed but should be adjusted down.

I'd go for anything non sleeve bearing. Either fluid bearing or double/twister bearing.

The F12's are some of the cheapest fluid bearing fans you can get.

Thanks.

I think I'm going to buy today on Amazon. How would you recommend I set them up? I currently have one case fan pulling hot air out of the case.

Thanks as always for your help.

Maybe I should just get the F12 PWMs for 5 pounds seeing as they ship to Ireland?

I am currently only using one case fan.

4 fans total should do the trick.

1 front and side intake, 1 rear and top exhaust.

No need for pwms unless you need to use molex or fan splitters adapters. You can get sata power or molex power to 3 x 3 pin fan connections.

When you say one front fan exhaust, you mean the fan is pulling the warm air out the front face of the case? As in, the direction towards which the DVD opens?

BloodBath wrote: »

No I said front and lower side intakes. Taking air from the front and side and exhausting them out the rear-top and rear.

Makes sense! I understand now. I have two fan sections on the side and on top. Perfect!!!

Thanks man, you're always a great help.
