The Heavy Weight Mega Vs The Light Weight H50

vs


I have owned a mega since I built my system last month, but wanted to test it against the H50. I have finally finished all the tests and the graphs have been updated with the new info. Based on my results I got better results by pulling air from inside my case and exhausting it out the rear even though Corsair suggests you to do it the other way around.

IBT(Intel Burn Test also known as Linpack) has been run at High to ensure the same amount of ram is used in every test and this is the test I used to find the max load temps.

I tested 3 settings:Stock, 3.9ghz with HT on, 4.1ghz with HT off
I ran 4 variations to these 3 tests: Idle, Window Panel, Fan Panel, Gaming
I even threw in the GPU temps so people could see how the panels and coolers affected the temps of the GPU during normal game play. I don't think the gaming/GPU results were very accurate though, I feel they varied some based on the maps played. I should have just ran vantage, but o well.
UT3 was the game used in all the gaming tests

This was not a stability test, the testing was only done to see temps.

Test System:
i7 860
CM Storm Sniper
Asus Maximus III
Geforce GTX 295
Windows 7
IC7 thermal paste
Ambient temp 20c
2x Ultra Kaze 3k @ 100% Push/Pull used on mega and H50

Pics of the system:







What I did was averaged the 4 cores temps I got to give a straight average for each test, however the detailed results are in the 2nd post. I took screenshots of every test ran showing: temps, cpu verification, IBT verification, and GPU temp verification and the link to them is also in the second post.

I put together graphs for easy reading, but as I said before if you want detailed results just read the 2nd post.




Quick Brake Down:

Stock
IBT- Mega wins
Gaming- Mega wins
Idle- H50 exhaust wins

3.9ghz Hyperthreading On
IBT- H50 exhaust wins
Gaming- Mega wins
Idle- H50 intake wins

4.1ghz Hyperthreading Off
IBT- H50 exhaust wins
Gaming- Mega wins
Idle- H50 exhaust wins

As you can see they both trade blows, the mega does better while playing games when only part of the cpu is used, the H50 exhaust does better during the Intel Burn Tests and they swap blows on Idle(but Idle results are very inaccurate no matter how you look at it).

Pro's and Con's

H50 Pro's
*Small- Good for smaller cases and ram with high heat spreaders
*Good for window cases- Temps are the same in IBT with side fan & window
*Easy to Install
*Good price/performance ratio

H50 Con's
*Push/Pull on 38mm fans difficult to mount- had to use zip ties
*Pump could go out/unit could leak

Mega Pro's
*Better cooling if running your cpu on stock settings
*Had lower temps while gaming
*Easy to Install
*Good price/performance ratio

Mega Con's
*Big- May not fit in all cases
*Need for good airflow- If your case has bad airflow it might not cool as well
*May have to pay extra for mounting brackets for your cpu
*Have to pay extra for 38mm fan clips or make your own if using 38mm fans

Conclusion:
Both coolers appear to do great for the money. I think it just comes down to case airflow, case size, ram size and personal taste in looks. I do not see either of these 2 coolers achieving a higher overclock then the other.

Discuss freely and enjoy looking over my results


Edit- Keep in mind these results only speak for my i7 860 and results may vary based on case airflow and cpu type.

After seeing how close the results are I have decided to keep the H50. I like that its smaller and makes my system look better(imo) and somehow my gpu stays cooler using it.

very nice review/test. although, as you stated, id like to see a push/pull on the h50. i bet that would drop the temps a C or 2

+rep. thanks. this is an ongoing battle.

Wow, the H50 is actually holding it's ground!

Ok, so the Megahalems is cheaper and you don't have to worry about leaks, but I bet the H50 is a lot quieter.

Depending on the availability of heatsinks when I go i5 I might just consider getting one.

Actually, the Megahalems is more expensive because you need to buy the fans. The H50 cost like $60 versus $60+$15 (fan). My San Aces alone cost $36+$60 (actually $45 for me) for the Megahalems.

Liked that fact that you used a 38mm fan to cool the Corsair Rad. but at the same time the price would increase.

I agree, its a good testing you have done...dude.

Great job mate


If people would look at the H50 at another good, solid, (different), air cooler and not a way to replace a true water cooling setup then I think these tests show great promise for the versatility of the H50 unit as a whole.
The real fun is going to happen when the push pull is added.
The one thing I have noticed in my unit is the space that is saved verses the big Mega.
Anyhow I cant wait to see your results when you add the push pull to the H50
as I will be doing mine tomorrow.

The H50 testing was done with Push/Pull

Pull air from outside the back of the case and the 2nd fan was pushing the air through the case.(This is how corsair suggests)

My next test's will be Push/Pull...Pulling air from inside the case and pushing it out the rear of the case.

Very nice comparison, +rep!

In this pic:


Do you have 3 fans attached to the Megahalems? 2 on push and 1 on pull? Does the furthest fan not touch the RAM?

It's a 38mm fan shroud and it made absolutely no difference in temp

It sits about 1/8 an inch above my ram

It should help, but the problem is that the radiator already has 2 fans on it. I can't add a 38mm shroud because there is not enough room between the fans and the coolers base. I may could add a 25mm or a 12mm shroud, but there is def not enough room for a 38mm shroud.

someone already posted their results in regards in utilizing a shroud and the result didn't mark any improvement.

If both cost 60 dollar being stock.
Then the H50 is cheaper.
Seeing we here are on Overclock.net
You want a good fan on your CPU cooler.
For the Megatron, this requires you to spend some cash(lets say 20 dollar) on a good 38 MM fan. Keep in mind that you need a fan with this cooler, no fan = no fun.
You need to spend the same money for the H50 in order to recieve the same good fan.
Therefor, for someone who wants a good fan on their CPU cooler, the price is the same.
Seeing the results not differ much, its up for personal taste.
I am an owner of a Megahalem, and it has the rep of being King of Air coolers, but still I would wanna test out the tiny H50, just for funs : )

For anyone who says, its cheaper to just use the stock fan of the corsair rad.
Stock cooler is even cheaper baby. ( yeah free thats right )

H50 - $65 (On sale @ bestbuy +tax)
Mega- $81 (Mega+1156 brackets+38mm clips+shipping)
2x Ultra Kaze fans - $25 (newegg 10 each + shipping)

Total for Mega= $106
Total for H50= $90

If you don't need brackets for your cpu then you save $6
If you pay full price for H50 then the price is about the same
