Thermalright SP-94 Copper Heatpipe Heatsink
 

Liquid3D and I take an extensive look at Thermalright latest and possibly greatest P4 heatsink!

Wow, great stuff!

It's very impressive that it beats the SLK900 by approx 2 degrees, but the SLK900U has the advantage of being both AMD & Intel cooler.

Is the SP94 being sold in belgium yet?

Haven't seen it in Belgium yet, but the price will approx. be around this one I think

I will put the SP-94 further to test the coming days by upping the vcore and see how much I can overclock my poor little 2.4 :)

are the temps in the review socket or diode temps???

the P4 has an onboard temp diode which we used for the measurements, it portrays the exact cpu temperature more correctly.

ooops! ... why does the heatsink have such a rough surface?

Look at that surface! :puke:
You can clearly see the machine marks in the scanner image, yet
the reviewer has praise for how "smooth" it is. ... huh?! :wtf:

Hasn't the reveiwer seen a really smooth contact surface? :wtf:

the scanner image surpasses that of most digicams, and even if I would scan a "smooth" / "lapped" heatsink, you will see the same marks
at 1600DPI things become pretty big , and the smallest groove can be seen as if it were huge

here are the L1 bridges of an AXP @ 1600DPI
:grin:

swiftech?
 

this review would be perfect if was set against the Swiftech MCX462-V, i mean dont we all wanna know who's the better one atm? :]

it would be impossible to compare it to the Swiftech MCX462-V... as it is a Socket A heatsink :*

the Intel version will be released very soon.

woops minor detail i hadn't noticed :] looking forward to the review tho ;]

we will try to do what is possible, as it is very hard to get our hands on Swiftech products here in Europe (tried France/Netherlands/Germany/Belgium to no avail), hoping for some good news from Swiftech directly soon :)

do you think its an impressive heatsink? i dont

its not like it blow's you away cause of his cooling..

the slight diff with the 900 is kinda weak.

why i still think that the 900u is better, cause it can be used for P4 & AMD, what is a good thing, cause most ppl cant say they will buy 101% sure again an amd or P4 [you never know what offer you will get :) ]


c wut i mean?

the cooling capacity of the SP-94 increases when used with higher Wattage.

Meaning that a P4 @ 3.6ghz with 1.6v will have a BIG difference with the SLK900.

the heatpipes cause this positive effect, this heatsink also has the SLK900 beat for easiness of installation!

that's just i minor thing the installation (imo)


ok, @ high oc it performs good (very good)
that means its more an OC heatsink then a standard user heatsink, but how many ppl know that? even after reading some review's.
in my humble opinion =>
hard oc'er => sp 94
all other pc ppl => slk900u

I still have to test this more profoundly before I can assure that the following statement is true: but at very low fanspeed, the SP-94 is also a better performer, the heatpipes can cool down the CPU in a small case where not a lot of airflow is possible.

But like I said, more test need to be done before I can be 100% sure. I'll be back with numbers & details in due time!

:super: ok :)

has somebody spotted them in a Belgian shop yet ???

I've got a Swiftech MCX 4000 here, with papst 4412FM @7 volt.
Now I've got some questions for you guys:
- Is it worth upgrading to an SP94 (is it worth the extra €59)
- Can I fit my 120mm fan on the HS?
- Will it fit on my P4C800-E Deluxe mobo?
- Does the possibility exists that i can overclock my PIV 3.0Ghz even more than 3.5Ghz (stable speed at the moment)

Lots of thanks in advance.

Mvg, Bored

where did you get that p4c900?
I've been looking all around for that board :^D

Ow, sorry, typo ;)
Correcting rigt away ...

Now, can we get back on topic please ;) ?

Mvg, Bored

it you are looking for the EXTREME performance... yes
otherwise = nope

Have you done any comparisons with other heatpipe heatsinks? Like the coolermaster and such? Would be interesting to get a value comparions (price/performance)

Coolermaster's HHC-001 Heatpipe heatsink is on par with a Swiftech MCXC370
http://www.frostytech.com/articlevie...id=1128&page=5

a little better then a Volcano 7+
http://www.3dxtreme.org/coolermasterheatpipe2.shtml

and afaik this Coolermaster seems to be for AMD only :/

sp94 and as5 will be available @ tones this week

avalon, you work at tones ?

Talking about AS5.
What TIM will perform best?
-AS5
-CoolerMaster premium (shinetsu)
-ShinEtsu by G51(or whatever the number is, allways forget it)
-Nanotherm PCM+

got AS5/Ceramique/Coolermaster Premium/AS3/AS-alumina up for testing here, if anybody can get me some PCM+ I'd be happy to include it in the roundup :)

I enjoyed reading your review and was wondering if you could clarify something for me.

In your article you wrote that:

"As a last test I set the CPU to 2.4Ghz, removed the CPU fan and let the system run like this.. for more than 1 hour! The CPU temperature was only 53°C."

Is this in idle or while running Hot CPU tester Pro?

at idle, at load it reached these temps in a much shorter time period :)

Dag, well I should have known it was too good to be true.

heh, I commented on your results at www.silentpcreview.com and they said it was idle as well.

Still looks like an amazing heatsink, great review by the way!

Thanks for the :super: comment!

placing a silent 120mm somewhere near to heatsink that blows cool air onto will make it very good performing though :)

I liked your idea of using it in a desktop case; I have a coolermaster atc-600-VX1 and was thinking of upgrading to a 2.4C. The airflow is not as good as in a tower, but it's a lot better than most other desktops.

120mm would do it, what's a good quiet 120mm?

can't answer that one, I'm used to 120mm delta's :)

a delta on a rheo kit: the power off delta and the silent off papst

papst are quite expensive but silent, or get an cheap enermax and use the potmeter ( same as rheokit )

yeah prob. papst or panaflo are the best. I use Papst 80mm with a zalman fan mate and heh, ADDA 60mm case fans that are suprisingly quiet.

Throw one of those 80mm or a 92mm on the sp-94 and you'll cool in peace.

whoops, "unregistered" is "Trip"
