Prolimatech Megahalems

[imported_trajan]

Sorry I'm having trouble even with the very detailed (thank you!) descriptions of how to do this.. Any chance of getting a picture? I think once I see what the result is supposed to look like it will be very easy to see the step by step and how to get there. Regardless, thanks for all the info!

EDIT: I think I found a picture from another thread, is this the sort of rig you're describing?

Yes, I also link to that picture from earlier in this thread. The fans are all backwards in that picture, otherwise you can follow it.

Hmm. Wish they would have thrown in the Sunbeam Core-Contact Cooler just to see how it compares. I'm sure it wouldn't win the shootout but I'd be curious to see where it ended up.

Here's a link to a review I did this morning on the Megahalems

Megahalems, installed with two fans using cable ties

The mounting system is best I've ever seen. However, the sag as the weight bent my motherboard was disconcerting. My last motherboard died for reasons unknown, it could have been similar strain from my TRUE.

Made me think, why can't the backplates have a long tail for leverage, to prevent this? Or why can't we drill extra standoffs for the cooler? In any case, I rigged a harness with #22 solid insulated wire and a cable tie, far easier than either of those ideas (the cable tie rachets nicely to just the right amount of lift) and now I'm happy.

This is in a Mountain Mods case. I used 1.5" 6-32 machine screws and nuts to secure my fans (8-40 also works, after trying this one cannot go back), and this gave a nice top anchor for the cooler harness.

Unlike the TRUE, the Megahalems doesn't come with any anti-vibration silicon strips to go between the cooler and the fan(s). Perhaps not necessary, but I have two kinds of fan silencers on hand. The FrozenCPU silencers don't extend beyond the width of the fan, so they just fit into place, as shown above:

FrozenCPU fan silencer

The Prolimatech thermal compound was a pleasure to use. I went with the xbit theory, thinnest possible film to even out surface without creating thickness. My Q6600 is lapped, so I was just "wetting" the surface; the stuff goes on arbitrarily thin.

I'm about to travel for a bit, so performance testing will have to wait.

(Yes, I know my fans are backwards, even the power supply. I don't use AC in the summer, and my office gets hot, so I'm exhausting all air out the top through a dryer hose, out a window. The Prolimatech is so I can still manage a mild overclock with 5V fans and this odd fan arrangement.)

What motherboard is that? Do those fans have enough clearance to be mounted properly and lined up evenly with the heatsink (i.e. not shifted up or down)? Are the fans touching/blocking any other components on the motherboard?

It looks like the fans are fitting just fine without blocking any other components, but it seems every other story I have read about the Megahalem indicates that most motherboards don't have enough room to mount a fan on both sides of the Megahalem.

Looks like a EP45-UD3P.

EDIT: i take that back. It's a Gigabyte, but the NB cooler is different than the UD3 models.

Close, it's a GA-EP45-DS3R. No clearance issues whatsoever, except for my fingers.

 

[onions]

Anyone found any clearance issues with mounting Megahalam on a EVGA 132-BL-E758-TR ATX Intel Motherboard. I ordered one on friday & totally forget that this mobo has a freakin black heat sink/something in the middle.. Hopefully it fits...

Probably very close. Take a look at x-bit's installation information on the P6T. You might be able to get away with turning the cooler so it's blowing air toward the top of the case (which they recommend anyway):

It's about time that manufacturers case and HS manufacturers come up with systems designed to hold up the HS.

What in the heck are companies like Coolermaster even thinking releasing something like the V10 and their own cases don't even have a support for it?

I mean, are they just effing nuts? At least for the time being give us some mounting holes and twist ties or something. The minute you lift a case with that cooler I expect to hear a loud "crrrackkk" sound of my MB snapping a large crack.

I mean how about a quick release at least? So we can remove it for movement. I would be scared to even put the tower on the ground near my feet lest a slight kick with my barefoot causes the MB to crack. The whole thing looks so precarious that it is even scary to look at.

I know I am ragging on CM, but it applies to all HS makers. They all need to come up with some support system that involves hooking the free end of the HS to supplied adhesive hooks on the roof of the case. Next I expect manufacturers who make both both cases and heatsinks to provide firmly attached metal or plastic hooks on the roofs of their cases.

Barring that, it really is time to consider making cases for O/C in a horizontal format. This "tower" form + crazy heatsinks is just irresponsible.

One would think especially of a manufacturer that makes both cases and heatsinks would have come up with a system that directly exhausts heatsink air out the top and actually creates some case - HS synergy. I understand that people don't want to limit themselves with the same manufacturer for case and heatsinks, but sometimes it makes sense to offer it. Some people will pay extra for a "system".

How about a heat sink that makes use of the whole area between the PS and HDD cage and then couples the whole thing to the aluminum case itself? Or one that hard attaches to the side panel and actually uses that whole panel for heat sinking and extra support?

Even the Voodoos and Alienwares of the world haven't done a decent case heat sinking system yet. Yet they justify their stupid pricing with no real benefits over a standard home build save for warranty. With those premiums you could build a spare machine as your warranty.

There just needs to be better thinking in high end air cooling. Nobody say water either, water isn't all that it's cracked up to be beyond effectively taking the heatsink outside the case in trade for a major PITA in terms of maintenance and worry. And I'm not talking about that joke Coolit Domino which half of owners say start to leak at some point. I'm talking about a proper Petra tech sourced 7/16" system with chosen components.

When every audio manufacturer for years has been using the case as heatsink for years now (and let me tell you, some of those 600w class A amplifiers dissipate 600w CONSTANTLY, so these 125w CPUs are chump change in comparison) and most of those products are smaller and have NO airflow inside them. There just has to be a better way.


EDIT: Just look at this beast: http://www.gumtree.com/london/50/41504950.html

I mean it has 8KW of LINEAR not SMPS power supply (much more heat dissipation) and 600w Class A means it must dump 600w of heat MINIMUM either into the surroundings or the loudspeaker cones. In any case 600w of heat will be produced somewhere in the system and that's assuming 100% efficiency. They don't even use fans. They are basically room heaters, and that's where I want the heat: OUTSIDE the case.

Here's the version that arrived in my subscription update email:

Sorry, and I know it's not your fault but is that test some kind of joke?

I mean what kind of idiots test heatsinks without running any load through the system? Did they test idle temps? How do we know what was running and what CPU usage was in effect?

Why the heck did they not run OCCT or SuperPi or Intel Thermal Analysis?

I realize that the relative merits of each cooler will be the same relatively speaking, but what use are the results with idle temps? I want to see how well these sinks perform UNDER LOAD. I don't buy a machine to run idle.

I mean what a major waste of having all those heatsinks in one place and a test system running all those tests when they didn't even test what matters? Man, what a waste of time some of these review sites.

Besides, only FrozenCPU has that Prolimatech in stock and guess who the biggest advertiser on that site is? The advertisement is on EVERY page.

What a sorry sham most of these "review" sites really are. I can bet an appendage or two that Anandtech would never release such a worthless "review".

It seems every time I try to research a part there is always some stupid fly by night website with a vested interest giving out results of "testing". It's just sad.

I realize that it seems I am making accusations here, but I am not. Instead I am just pointing the obvious relationship between these sites and advertisers and shops. Even AT forums is not immune with several useless Nvidia shills discovered here also a few years back. The whole time they would incite people and go crying to the mods when someone said something they didn't like. I can't believe we even let them still post.

I guess the old adage "keep your friends close and your enemies closer" does apply here though. At least we have a better chance of knowing if these shills sign up with a new user name, since at least we can track their IP addresses.

It's just a sad state of affairs in any hobby these days.

From the Benchmark Reviews review:

EVEREST Ultimate Edition v5.00.1016 by Lavalys was then utilized to create core loads and measure each individual CPU core temperature.

After taking the time to reread the review and find this line, I see here that the original post was edited, and a new rant added. Isn't one supposed to leave soda in the fridge for 24 hours, so it doesn't fizz over when you open it?

 

[zagood]

well at least he apologized.

 

[max347]

Sounds like he just has some built up frustration...
