Introduction

Alright, let’s start our introduction. Geert from

target='resource window'>MPL has again sent us some cooling products for a

review. After we had

href='/index.php?page=articles&num=41'

target=resource
window'>two GlobalWIN fans (the CAF12 & CBF32) over for a review last week,

year, century, … whatever you like, I thought it was about time to take a look at

some JustCooler products, the HD-100 5.25′ Bay Cooler & the HD-600 HDD Anti-Dust

Cover Cooler. These hard drive coolers may look useless to many of you, but bare in

mind that a hard drive is an essential part of the computer, and should not be

forgotten! Especially the latest 7200RPM, 10000RPM and 15000RPM drives generate a

lot of heat which is dumped in the case resulting in a higher case temperature,

causing hardware instability and so on. The worst case scenario for a hard drive in

this situation can be ‘hard drive failure’ which means you lose all your precious

data. I experienced this myself earlier this week (even with good hard drive cooling

installed!)


Well, this looks like the perfect job for these JustCoolers! Let’s have a

look…

I like to note that the JustCooler HD-100 hard drive cooler is shipped in a

solid box together with all the necessary screws and connectors you need for a

proper installation. The HD-600 package, however, doesn’t include any screws to

mount the cooler onto the hard drive. :(

My First Impressions


HD-100

The JustCooler HD-100 uses two 40mm fans that push around 5CFM each @ 2500RPM.

That gives us a total airflow of something around 10CFM. The fans are mounted behind

a plastic grill with a dustcover (filter) underneath. This dustcover prevents dust

from entering your case while the fans are working. Mounting the HD-100 shouldn’t

give you any troubles at all; you just have to take off a free 5.25′ face plate.

Then you simply slide the HD-100 into the selected slot and screw down both sides of

the cooler to the case chasis. The HD-100 fans have to be powered by an ordinary

molex connector. Plain simple, huh! With its 24Dba, the JustCooler is a very silent

cooler, so your Quake 3-concentration won’t be disturbed by the noise of this

cooler.

HD-600

The JustCooler HD-600 uses just one 55mm fan @ 3500RPM to create an 18CFM air
delivery. The HD-600 is even more silent than the HD-100, probably just because of

the fan’s lower RPM.(I can’t give you an exact Dba number because JustCooler hasn’t

put it on the specs part of their site) Mounting the HD-600 is also very easy; if

you can open a case, you can certainly mount this HD-600 onto your hard drive. You

just have to take your hard drive out of your case and put it on a table with the

bottom faced up. This way you can put the HD-600 onto the hard drive and screw it

down with 4 bolts. That’s all; now just reinstall the hard drive along with the

cooler into your case. Just like the HD-100, the HD-600 fan is also powered by molex

connector.

That’s about it for the specs, let’s head over to the tests…

Testing

System setup

- AOpen HQ45 case

- Asus CUV4X motherboard

- Intel P3-700E @ 1008Mhz (7x144MHz)

- 128MB pc133 RAM (cas 3-3-3-5)

- Western Digital UDMA100 7200rpm 20GB

- Creative Geforce DDR @ 150/350

- Win2k (SP1)

- Directx 8 final + Detonator 6.47 + VIA 4.25a

The Results

The first cooler in this test is the JustCooler HD-100. Before I installed

this one in front of my Western Digital 20Gb hard drive (more specs above), I almost

couldn’t touch the hard drive because of the instense heat. OK, maybe I’m

exaggerating a little here, but I believe you get the picture, right? After I

installed the HD-100, the hard drive didn’t become warm anymore; not even a bit.

Another great thing about the HD-100 cooler is that it sucks fresh air into you

case. This resulted in dropping my case temperature by about 2C (temperature

measured with the Asus PC PROBE).

The second cooler I tried, was the JustCooler HD-600. This cooler clearly

performed a lot worse than the HD-100. The HD-600 only cools down the bottom of the

hard drive instead of blowing air over the entire hard drive (like the HD-100 does).

Another bad thing is that the HD-600 uses the (hot) air inside the case to cool down

the hard drive instead of sucking fresh air into the case (again, like the HD-100

does). All this resulted in the hard drive still being warm at the top even when the

HD-600 had been working for a couple of hours.


JustCooler HD-100

Good

- Great performance

- Value for money

- sucks fresh air into the case

- Easy mounting

Bad

- Loss of a bay


JustCooler HD-600

Good

- Easy mounting

- Doesn’t take up a bay

Bad

- Very poor performance

- Uses (hot) air from inside the case

Conclusion

Although these two coolers are made by the same manufactor ‘JustCooler’, they

are both very different! The HD-100 is a very efficient hard drive cooler, which can

take good care of your precious MP3z and nude pictures and it’ll even lower your

case temperature by a couple degrees. Then we have the HD-600, this cooler (if we

even dare to call it a ‘cooler’?) is the worst hard drive cooler I’ve ever seen in

my entire life! Oh man, if you’re desperate to buy a JustCooler hard drive cooler, I

suggest you go for the HD-100. If the manufactor doesn’t have to be ‘JustCooler’,

I’d say you better check out the
