I don't know why is there an argument here... Towers rule! Hardly anyone uses desktops (flat cases) any more, aside from using them for media PCs underneath TVs. That's why some of the case manufacturers are still selling them.

If you really want to have a PC that's thrifty in power, easy to cool, lesser fan noise and save space, you could get a nettop, which uses low voltage CPU and internal hardware that are extremely efficient thermally, electrically, and ergonomically.

People who are interested in towers are people who want true desktop hardware and more emphasized in performance, rather than saving power / space / noise.

Towers provides more space for cooling hardware (vents / fans / heat sink / water cooling). Provides more surface area for cooling. Provides more space for computer hardware (more drive bays and PCI slots). Provides more flexibility for ergonomics internally and externally.

Flat cases don't even make sense for PCI slots, either need to have a riser to make them horizontally. Or need half height cards to fit the low profile space. Like you already said, lesser drive bays, too. Some have proprietary size PSUs, that's hard to obtain and unreliable. Lesser surface area and space inside for cooling hardware. Just too many deficiencies in comparison to towers.

As for the CPU heat sinks, there are many different designs to fit your purpose for cooling. Some heat sinks, like one from Zalman ( http://www.newegg.com/Product/Product.aspx?Item=N82E16835118019 ), actually pushes air from front to back, conforming to the air flow of a tower. There's no "more heat on the top of sink" issue for those type of heat sinks.

First Of all the comment about Chevy was a metaphor. Not to be Taken as direct statement. And anyway this whole thread has gone completely the wrong direction from my original question.
Why aren't computer cases built to use heat sinks the way the manufacturer intended?
Heat rises. It doesn't move side to side without forcing it to. If you look into the time line of enclosures, all these extreme cooling methods didn't really hit mainstream until towers were the main staple for sales. It wasn't because they were more efficient, it was to reduce clutter
on top of some ones desk. If something is built right it is built right. That is why the desktop enclosure hasn't changed all that much in the thirty years or so that they have been available, but there are thousands upon thousands of towers. Every one of those manufactures are saying they have the best method of cooling for their towers. All the while the lonely little desktops are sitting in the back just doing what they do without any real concerns for updating or competing in the mainstream market. The only reason they have become more expensive is that they don't share a larger piece of that market. That is economics. These companies want to make a profit on everything, which is their right.

Besides after all this debate not a single one of you has given a concrete answer. Just a bunch of opinions. So go play with your towers I don't care to hear your opinions, but
if you can come up with a real answer instead of your indoctrinated b.s. I will gladly listen.

Lets do a little science project.

1. Get a plastic cup
2. Get a lighter
3. Fill the cup with water
4. Hold the cup in the in one hand and place the lit lighter under the cup.

Wow the cup doesn't melt that is because the heat ( that rises) get absorbed by the water and dissipates up and away.

Now turn the whole thing on its side. Whats happens then is that the cup will melt because heat still rises and will not be dissipated by the water no more.
Also you will probably end up with a wet crotch.

The funny thing is that I am planning to build a new pc soon and I to will be using a tower.
Because I would like to have space for the component that I want to use.

But like I have said to many times to count and for some reason not single person has even considered the answer is WHY AREN'T HEATSINKS BEING USED THE WAY THEY WERE INTENDED WHICH IS THE UPRIGHT POSITION.

Because it makes such minute differences it doesn't matter.....as I stated earlier.......heat will dissipate through a heatsink horizontally as well as vertically in such a small quantity.

Look at video cards...heatsink is on the bottom side...so the heat from the GPU has to travel down....if it really mattered they would put the heatsink on top of the card when it is in a tower case...but it makes such minute differences it doesn't matter.

>> Re: Heatsink Reviews .. interested?
But you would think that even if it is only a minute difference that it would have been taken into account a long time ago. Even video cards have puzzle me because of them being built upside down. It would have been just as easy to have designed them to face upward.
And I am sorry heat does not travel just as easy sideways as it does upwards.

If you take a long piece of pipe and place a heat source at one end the other end will take much longer to heat. The heat will disperse faster from the end of the pipe with heat source.
If you take the heat source and place it in the middle of the pipe the heat will then disperse more evenly across the entire length of the pipe.

Depends on the size of the pipe...in terms of a heatsink pipe which is tiny, it makes hardly any difference....especially with the type of heat...direct flame will heat it faster, while heat produced from current won't.

If it did make that much of a difference, video cards would have their heatsinks on top......but they don't...because it doesn't

You are talking about convective cooling of fluids, in this case air. Hot air rises, cool air descends. You are correct about that. That is a natural phenomenon under no influence of other external forces.

A passive heat sink dissipates heat in two parts: one, heat conduction through solids, in this case metal; two, heat convection through fluids, in this case air. Heat conduction doesn't matter what direction, be it side way or upside down, heat goes from the hot side to the cool side naturally (gradient / equilibrium of heat transfer). Heat convection is described in the paragraph above. In this case, naturally an upright position for the heat sink will be beneficial for cooling.

An active heat sink dissipates heat in two parts: one, heat conduction through solids, in this case metal; two, active heat dissipation through the flow of fluids, in this case moving air. Heat conduction is described in the paragraph above. Active heat dissipation, in this case is carried out by fan(s), which moves air through the metal fins of the heat sink. It doesn't matter what direction the heat sink is mounted, as long as air is forced to go through the fins to carry the heat away from heat sink. It's no longer a natural system as it adds external forces to actively facilitate the movement of fluid.

So after investigating this on several other reputable sites I have discovered that we have all been wrong to one degree or another.

Different types of heat sinks require different orientations. You basic OEM heat sink doesn't really care what position it is in or what type of case you have. The case just needs to be properly vented. Heat pipes do care Gravity effects their efficiency. When mounted horizontally You create air pockets above the liquid inside which results in less effective cooling. Mounted vertically the wick effect does its job and results in a well cooled cpu after that the case just needs to get pulled out of the case. Liquid cooled really doesn't care its more about getting the liquid moving fast enough to move heat to the radiator and let fans do the rest.

I could keep going but I am tired of arguing. So the end result which is just a matter of fact that none can argue is that the heat sink you chose is dependent on its orientation and more efficient cooling of the cpu can result in desktop with right kind of cooling. Also a tower can be effective with the right type of heat sink or pipe. Just going out and buying one that looks cool and slapping it in there which I admit to have done when heat pipes first came out, and when I did that in a tower setup The results were no better than a OEM heat sink. That is what has always puzzled me.
So there you have it I apologized to all offended if any, The next time I have a question I will just keep it to myself or post it to a site that has more than 3 registered users at any given time.

Wow......... I have been gone all day... preparing for a face to face interview this morning and then the actual face to face interview this afternoon.... heres to my fingers being crossed and praying to God that I land this job.


Yo Carl..... if anyone around here that has a real say so between desktop or tower cases... then it would be me. My first 5 computers have been desktop models and today I have a tower case. I have real experience with the difference between the two when it comes to heat, space, efficiency, cost, capacity etc..... But it is way to much info to write it all down here... So please call me (i pm'd you) and I can tell you my experiences between the two. I hope I can share some enlightment with you.

Also, I had the same questions as you do with cpu heatsinks but now I understand more after talking with different techsupport from cpu manufactures that I would like to share.

Here to show you that I am not blowing hot air are a couple of links to my previous systems that uses desktop cases and a link to my current system...


My previous systems (desktop format) -

@ Codisha http://www.codisha.com/reviews/ac/sunbeam_twister_120/review_s...120_p1.htm

This is the one of the latest from Sunbeam and has been released on it's own mainstream brand instead of the Tuniq enthusiast brand.

the twister is a pretty interesting cooler with it's Turbo fan design and offers good performance

Hope this makes sense...

I'd be interested in some comparisons between ANY air-cooling heatsink/fan combo you test and itself...with the difference being the stock fan that came with it replaced by a higher-CFM/M3M fan.

And/Or another comparison where the stock fan is replaced by a quieter quality fan and both tests running the fan at 12VDC (=max RPM). Whether higher or lower CFM/M3M is not a concern...just interested in cooling results with a quieter volume fan at a given fan's max RPM). Note that some fans provide more CFM with lower RPMs due to blade and/or bearing design, and some fans with lower RPMs still produce more noise.

Basically, looking to see just how much difference is attributable to fan air volume changes for a given heatsink assembly, and when possible, obtain another set of data to determine if a quieter fan can be substituted that will produce superior cooling.

thanks for the interest john. that is pretty much exactly what we (i) do with our tests.

the sample undergo a serious of tests with different configuration settings. from stock to a medium OC to a bit more of a high OC.
we test all configurations with at least 2 different fans. the two fans we choose are the Scythe Gentle Typhoon 15 and the SanAce xxxxxxx1011. we choose these fans as they have been the fans choices in a wide range of enthusiast applications as well as extreme cooling applications. the GT is an excellent fan with great performance and a real world reasonable sound level and because of it's ability to supply a good amount of back pressure it is often a choice in water cooling applications as well.
the sanace is the high or ultra performace fan. it's used when noise or sound level do not matter. this fan is 38mm thick and blows at over 110 cfm.

we are also include the factory supplied fan to keep things in perspective. the 2 pre selected fan will give the tests more constancy and achieve exactly what you had in mind.
one test setup that would show the coolers performance at low noise/ high performance levels and one test that would show the coolers performance at high noise / extreme performance levels.

hey, i would personally request you review a cooler that gives the most bang for buck..
i mean in the sense that you go on newegg, think like a greedy little pc builder, and pick up a really cheap cooler that seems like it could really hold its own.. limit the budget, and use your witts from your PC cooler reviews and find a cheap but good looking cooler. Don't pick one because its cheap, but because it looks like it might have some good cooling capabilities.. you know what i mean? not everyone can afford being a pc builder, so you would attract alot of attention to those on a budget.

I would definetly read it then! me spending money divided on several computers, i cant afford to put all highend parts in each of my 5 computers..

but but, fora budget cooler i would say 50-60 dollars at the absolute max..

cheers mate! :D
