Ok I've always had a TT Volcano 7 on my system....never had an issue or problem with it...but reading reviews on the 7+ and seeign some peoples results...got me very intrigued......

Now With the Volcano 7 my CPU Idles between 29 and 30 degrees Celcious..thats an AXDA Thoroughbred 1800+ @ 2000+ defualt voltage....and full load will never see over 34 Degrees Celcious......

SO Yesterday I went to my local computer store and picked up the TT Volcano 7+ anticipating a better temperature.....the thing looks nice and is really heavy and the design looks well thought out......but..its WORSE temperature wise than the Volcano 7.......well that is Temperature Vs. noise ratio anyways.....

CPU Idling with the 7+ at low speed the chip is at 35 Celcious!! Than and Medium speed its at 33 and High its at 30....but HOLY HELL is this thing loud at high....its unbearable.....

Right now I stuck my Volcano 7 back in and shes running full load for 2 hours now at 34 Celcious...in order to get the same temp. id have to have the 7+ at High...and its more than 3 times louder than the 7.....

What gives???? I mena i paid $40.00 CDN for this 7+ and i cant return it now...and my $20.00 6 month old Volcano 7 is better..........why is this..???

I honestly have no idea, sometimes an HSF, or a CPU can yeild different temps.
Really, anything can.
The V7 also adjusts automatically, while the V7+ has manual control, and medium is already loud IIRC.

Were both using the same paste?

I know a CPU can yield different results yes.....but a HSF?? maybe within a degree or 2....but not like this....

The Volcano 7 adjusts speed according to ambient temp. read by its Thermal Probe...at a misely 3200 rpms it cools better than the Volcano 7+ at Medium speed and is quiter......the 7+ WOULD be better overall if i left the fan at full speed and under 100% constant load but its LOUD...thsi is what doesnt make sense as the Volcano 7's heatsink is all aluminum with a copper contact plate/base and the Volcano 7+ is ALL copper.....i know the 7+ HSF is smaller the the 7....but after readign all the reviews and everything...my god...this 7+ should be cooling a lot better than its baby brother the 7.....

As for the paste.....ive tryed 3 different types on BOTH heatsinks....the worst type was the stuff that came with the Volcano 7+....its so milky/watery and its crap........3 degrees worse than AS3.....i have another white thermal compound which i always use which in my applications have yielded the same results as AS3 so i stick with this white paste I have.....works as good as AS3 from my tests....

I previously had a Volcano 7 and got rid of it for the 7+. and my TEmps are better not worse. I usually leave it running @ medium Fan speed and temps are fine. I also found it alot quieter than the 7 during the summer. And I prefer the manual fan control. Which I bought a PCI slot switch for it works great. The all copper base is alot better than the copper insert in the 7.

also which motherboard do u have in your system.
is it reading temps from the XP diode, or the socket temp?

Yes, I have a feeling the temps he reports are from the socket as well. Perhaps 34ºC really does come from socket. If his new motherboard does report 34 as well, then I'll be really surprised.

The board is an ASUS A7S333....
And it reads the temp. from the integraded Thermal Diode on the CPU....says so in my manual.....

Anyways I Verified the wierd temp. occurances i was having by popping the 7+ onto my Server which is a AXP 1600+ system running with 1.90VCore at 1.7GHz....with the Volcano 7 at full load it ran at 43 Degrees Celcious....now with the 7+ at LOW speed it idles at 46 degrees celcious....at medium its at 43 celcious same as the 7 does.....and at high it was 39 celcious...but the noise was just UNBEARABLE.......so i left it at LOW for now.....

My finds r that the Volcano 7 cools just as good as the 7+ does while the 7+ is at Medium speed the thign is though that its louder than the regualr Volcano 7......at HIGH speed the 7+ is definently better as i cant set the speed of the fan on the 7.....but the noise is terrible.....

The problem is that the Volcano 7+ is smaller. If you had an 80MM 7+, chances are it'd cool better than the V7 and at lower speeds, therefore less noise. The Volcano 9 is big but goes for Aluminum, so it should be cheaper than the V7 but with temp control at 80mm.

Well i cant make a Volcano 7+ 80mm.....i can make an Adapter and use a different fan but with the 7+ heatsink....

The volcano 9 is a big waste of money..it looks ugly and performs worse then The Volcano 7 and 7+ but for $10 more than the 7 and $10 less than the 7+.....oh well....

I just wish the 7+ could be quiter.....i mean.....i just got the 7+ cuz liek my system is already pretty quite with the Volcano 7 spinning at a misely 3200 some odd RPMS but i thought the 7+ was moer efficient so i was hopign it could be even QUITER with a lower speed settign of the fan and a more efficient Heatsink itself.....turns out not to be that way......hmm......

I dunno, sometimes it's the design, the dynamics of the fan blades that makes the difference. And also, small fans do more high pitch than filtered Volcano 7 sound. The retail Intel P4 cooler seems to like high pitch at 2200RPM, though the P3 retail was the worst (for my uncle's P3 733 at least). Why don't you take off the V7 fan, mod it on the V7+'s HSF?
You will then use full copper with the great cooling design of the V7 fan!

It's the whole deal between copper/aluninum. Copper really lets the heat sink in, but it doesn't dissipate it well without a lot of airflow (hence louder fans). Aluninum however, can do cooling well even with low airflow, it has very high heat dissipation. That's why a lot of the models are hybrid aluminum and copper. But for the very best cooling, you're looking at heatsinks the Thermalright Sk and Slk series, which are large, have pure copper, and dedicated airflow. The Swiffies and Alphas have a copper base (which i'm pretty sure is welded to the pins) with aluninum pins, which works good with a high or low rpm fan. The same can be said for most aluninum/copper hybrid heatsinks.

Instead of Rdram, why not just merge 4 Sdram channels...

Since when does aluninum have higher heat dissipation than copper?

And if aluninum has better heat dissipation why are all the best Air coolers using Copper bases?

no, it has better dissipation with lower air flow. Copper conducts heat better. Read the lines closer before you post

Instead of Rdram, why not just merge 4 Sdram channels...

My volcano 7+ will cool my 1800 at 35 C and usually just stays around that area. After gaming for a few hours the temp never usually changes. I try putting it on medium but the damn thing still cool/sounds that same as low. Another problem I have is why does my a7n8x say my 1800 is 1.153. How can I tell if it is running at 1.5?? Thanks.

change your FSB from 100 to 133

Instead of Rdram, why not just merge 4 Sdram channels...

Well dude Ambient...Case.....GPU..North Bridge they all affect the temp of the CPU....

Your 1800+ is at 1.1GHz cuz the FSB needs to be set at 133MHz..

My T-Bred 1800+ is OC'd to 2000+ defualt voltage....at constant 100% load its at 34 Celcious with a Volcano 7...

I can do similar results with the Volcano 7+ but at a MUCH louder DB level from the fan..

as for u not noticing the difference in the fan from LOW - Medium....i doubt that and if its true than u must be goign deaf........

And EDEN....I think I'm gonna try that....I'll try sticking the whole fan mounting bracket from the Volcano 7 onto the 7+ HSF....the only thing than is that the 7's fan has a amient temp. probe......do i cut it off and connect the wires to complete the circuit than use the 3 speed switch from the Volcano 7+ ?? or do i just stick than fan on and thats it ?
