Re: HOWTO: Disable Seagate DM001 APM Head Parking *Permanent

Looks like the guide may no longer apply to newer models: my DM004 has the APM Feature Set locked on Enabled, HDAT2 won't let me change it.

Re: Storage (In The Next 5 Years)

but even for storing movies, an average remux right now is around 25gb, a 4k x265 is already going into 60gb, not considering the super extended versions studios release on certain movies. That much is true, however it also seems media consumption is moving increasingly towards subscription/streami...

Re: HOWTO: Disable Seagate DM001 APM Head Parking *Permanent

Hello everybody, long time no see! I've got a decent deal on a Seagate BarraCuda 3.5" ST4000DM004: ideally, this is going to be used as both boot and storage drive on a small, lightly used file server running Linux, which is currently using a WD Green where I had disabled the head parking feature, t...

Yup the clearance is an often quoted problem, but in all the threads I've found, it never looked as if someone actually tried it in practice. But quiet PSUs don't move a whole lot of air, and maybe clearance is not /really/ that much of an issue. In fact I am more concerned with the effect on the ai...

Since you're planning to use a 3480, I should point out that at least 2 out of 3 users have reported a faint hissing noise coming from the L7 at times, which might be more noticeable than in other cases.

Less than a S-Flex @500 rpm used as a system fan (in free air or for a different application the same fan will sound quieter).

the OP made it clear that he's prepared to pay for a passive PSU if needed. And that's great, but that PC will have a single case fan which will provide the baseline noise: even the best 120 mm fan @500 rpm is not dead silent. As long as the PSU is as quiet or quieter than that (easy), it will stil...

Upside down PSU in Solo?

I'm toying with this idea to reduce the chance of hot air pockets around the PSU: but I think it may have several undesired consequences.

I seem to recall someone tried this already? What were the results?

The Value 430 is still among the most quiet PSUs SPCR have reviewed. Just because it's the quietest, it doesn't mean all the other PSUs have stopped being inaudible! 11 or 14 dBA make no difference...unless you live in an anechoic chamber! :) Plus, the Nexus is a 430W whereas the L7 comes in a 300W...

If fanless means a PicoPSU or WinMate, I second that. Fanless ATX supplies -OTOH- are hard to come by, expensive and inefficient.

Is the Nexus Value 430 more quiet? That PSU exhibits SciFi SPL, just 11 dBA, that only makes sense in an anechoic chamber. As a reference SPCR's own test lab measures ~17 dBA at night. The L7 is inaudible for me even in the middle of the night, but I don't live in an anechoic chamber :) However, th...

If seek noise is your only concern, you could try enabling acoustic management on the drives. As long as it's supported, the seek noise is reduced but some performance is lost as well.

Yes it is possible but you need software to feed the readings back to the T-Balancer, is because the thing itself wouldn't have a way to read those sensors all alone. So basically this means you need Speedfan and the Navigator open at all times to control fans unless you're using the probes as a bac...

There's one thing that all of these Silverstone case reviews make me wonder about.

Just how many replacements can you find for those 180mm fans if, for whatever reason, you need or want to get a new one?

The 120mm format is so very much widespread, there are fans for each and every taste. But 180?

If you lose the front exhaust and ramp up the back intake you could try to make it work in positive pressure. Close the holes on the back and stick a filter on the back intake and you've got rid of dust. It won't be as cool or quiet as a Solo or another well-designed negative pressure case, but I gu...

Yes, when I said it's pre-ATX12V I meant exactly it lacks the 4 pin power connector for the CPU. The board won't power up unless I get an adaptor. The PSU is an older ATX unit, pre 1.x specification, so the 5V line is stronger and the 12V weaker than current units. TBH I'm concerned about frying up ...

I'm re-building a machine on the cheap, and have an old 235W PSU lying around from the pre-ATX12V era; the 12V rail rating is 8.0A, or 96W. The machine would run an undervolted Winchester A64 and one 3.5" HDD, used to pull about 40-45W during normal operation. I'm mostly concerned with peak absorpti...

I'm thinking of one of these two cards to replace my aging 6600GT. Goals are: 1) lower power consumption 2) better 3D performance, in that order. My current card is both undervolted and underclocked in 2D (amounts to ~10W less than stock at the socket); how would the newer cards compare to my curren...
