how big a hsf for this? (how much C/W basically)

[eLiu]

I am probably getting a 1.2ghz@266 cpu...(tho a 1.0ghz isnt out of the question yet)

anyway, how much thermal resistance do I need? is 0.79 C/W (Celsius/watt) good enough? What if I overclock? Will that still be sufficient?

The unit itself is a "OCZ Glacier2"...which seems to be manufactured by Dynatron...the two prodcuts look identical *confused*

OCZ unit:

Dynatron:

at any rate, tcwo requires that i buy a cooler from them in order to get a 1yr warranty on my cpu (which i want, b/c im not necessarily OCing right away...at least, not yet)

Anyway, if .79 is not enough for an OC (to say, 1.3-1.5), would .5-.6 be? (PC Power and Cooling K1-A)

thanks,

alot of people bash the ocz copper gladiator,but i use one w/the Delta fan,and my full load temp never goes above 43c no matter what i do to it.i would recommend it.

The Glacier 2 is a smaller sink than the Gladiator. The two don't really compare.

A .79 C/W is pretty poor. Some of the great HSF's have CW's from .13-.20 and good ones are usually less than .40.

If you're going to overclock, consider something else. TCWO.COM apppers to sell nothing but junk for coolers. If you want a warranty, buy their $9 fan and immediately replace it with something decent.

For the money, you will probably be happiest with the Taisol 760092 or the Swiftech MC370. They seem to have the best rep around the board and people seem to get good performance out of them.

If you do decide to pick up anything from OCZ store, just be very careful of their customer service. Their rep here is horrible

[Renob]

badbry most people arent bashing the cooler their bashing the OCz online website for have the worst CS and support

 

[Richardito]

You can get a high performance, cheap Vantec HSF like the one I use (look at the signature). Expect to pay less than $20 for it from an online store.

 

[jonnyGURU]

Garoin... you don/t know what you're talking about.

Albeint, I'm not the biggest fan of the "Chrome Orb" (personally I don't feel it should be used > 1 GHz), the $9 fan is a Dynaeon and it keeps my 1 GHz cool at 1.4 GHz.

Have you ever used one? No. That's what I thought.

If you don't want to buy the fan... fine... live with the 15 day warranty. Just remember it's me on the other end of that RMA phone line.

 

[NightTrain]

The Glacier2 in your linked test had a 36CFM fan. It looks to me like the Dynatron comes with a 22CFM fan which would perform even worse. I would suggest paying the $9 for the 1 year warranty and buying yourself a real cooler. The one shown at tcwo looks like the stock fan that came with my retail 1.33 and I can tell you from experience that it's horrible. A Swiftech MC-370 will take at least 15C off it's best number.



And no I haven't used the Dynatron...I ain't used a gorb on my bird either. Think about it.

 

[jonnyGURU]

You are correct NightTrain...except for the similarity between the Dynatron and the retail fan. The retail fan pushes little to no air. It's horrible and I can't think of why AMD uses that unit. It's like the problem with the ThermoEngine. MY GOD! What were they thinking when they used that 18CFM (I'm exaggerating) fan on that thing.

As for the Orb, I roll my eyes everytime someone buys one. They do look cool, but come on. Then again, I roll my eyes everytime I get an email that says "when I boot up, I get a memory error. What can the problem be?". :Q

My post was directed towards Garion's statement that TCWO "sell nothing but junk for coolers".

The CPU fan that TCWO sells is rated by AMD to run upwards of 1.5 GHz. TCWO do not condone overclocking. If they did, they'd be like these other stores that DO CONDONE OVERCLOCKING and offer better fans, but yet only give you a 15 to 30 day warranty! (see my point?)

eLiu said, "which i want, b/c im not necessarily OCing right away...at least, not yet", which means that the Dynaeon WOULD BE a good fan to use. If he overclocks later, lose the fan and install a hair drier motor for all I care. As long as he doesn't chip the die, remove the serial number sticker, put Arctic Silver all over the resistors or peel off the rubber pads, it's not like they're NOT going to take the CPU back.

 

[Demon-Xanth]

.79C/W is down right pittiful. I have a .66C/W HSF sitting on my floor because I didn't trust it being on a Cyrix 300 M2

Wait a second. You are defending the selection of heatsinks at TCWO? That's pretty embarrasing - You sell a Chrome Orb and a generic heatsink that nobody has ever heard of. Even IF the Dynatron is decent, most performance-oriented people don't want a total unknown - Risking your $120 CPU on a $9 heatsink that could be fine or could be crap is pretty dumb.

By the way, I don't know what the Dynatron is, but it's definitely NOT a OCZ Glacier2. Check out the difference on the two home pages:

OCZ Glacier2
Dynatron

The two heatsinks have totally different specs and look very different. The Dynatron looks like a Coolermaster more than anything. Specs are not that impressive, with only 22cfm airflow.

In similar threads, JohnnyGURU, you've stated that your $9 Dynamat outperforms any Taisol. If so, this is the deal of the century. The ONLY time that anyone has mentioned this heatsink in recent history on Anandtech is when eLiu has asked about it. Do a search and find out. I find it a bit comical that your $9 generic heatsink outperforms one of the most respected brands in the business, especially their new copper bottom model.

I'd be a bit hesitant to start slamming people because they are trying to answer someone's question. I think that I gave eLiu a pretty good answer. If you want to overclock, go with something that a lot of people have used and liked, not something that's known as crap (the Orbs) or something that nobody has heard of for $9.

You guys want more respect at TCWO? Get a better selection of heatsinks. I look at your page and see junk and unknowns.

[NightTrain]

The Glacier2 also has a copper insert in the base.

 

[jonnyGURU]

Garion, What the hell is your problem?

I NEVER said that the fan was better than ANY Taisol. Absolutely, the CGK760092 is a GREAT cooler. But then again, I never said that Taisol DOESN'T make as good a cooler. That WOULD BE a dumb statement, but then again, I NEVER MADE THAT STATEMENT. I said that it was better than the more popular (due to &quot;affordability&quot; I'm sure) CEK734092. That is EXACTLY what I said... And using your own words, &quot;Go do a search AND FIND OUT.&quot;

Also, you think it's dumb to count on a heatsink that a company recommends because YOU never heard of it? That statement in itself is dumb. For the most part, we cater to the lowest common denominator. People putting socket 7 fans on Socket A's, or in some cases no heatsink at all and at the best effort, put's a Super Orb on their CPU without thermal compound AND manages to crush the die in three places! As I JUST SAID, &quot;The CPU fan that TCWO sells is rated by AMD to run upwards of 1.5 GHz. TCWO do not condone overclocking. If they did, they'd be like these other stores that DO CONDONE OVERCLOCKING and offer better fans, but yet only give you a 15 to 30 day warranty! (see my point?)&quot;

eLiu asked, and I'll quote, &quot;im not necessarily OCing right away...at least, not yet&quot; in which case the Dynatron for $9 is more than enough, and certainly the OCZ Glacier or a Taisol CGK760092 would be EVEN MORE than enough TWO TIMES OVER. NEVER did I ssay that they WEREN'T good HSFs!!!!

>>I<< said that >>I<< use the Dynatron to cool a 1 GHz running a 1.4, but NOWHERE did I say that he MUST continue to use it when he decides to overclock nor did I stad up and say that the $9 Dynatron is THE FAN TO USE if you overclock. Matter of fact DID I NOT SAY, &quot;If he overclocks later, lose the fan and install a hair drier motor for all I care. As long as he doesn't chip the die, remove the serial number sticker, put Arctic Silver all over the resistors or peel off the rubber pads, it's not like they're NOT going to take the CPU back&quot;?

Apparently you didn't read it, don't want to read it or DON'T GET MY POINT. Take your pick.

&quot;If you want more respect at.....blah blah blah&quot;



<< I'd be a bit hesitant to start slamming people because they are trying to answer someone's question. I think that I gave eLiu a pretty good answer. >>



You did give him a good answer, but you used calling a heatsink YOU KNOW NOTHING ABOUT a piece of junk and I WILL take offense to that. You can say that this fan and that fan are BETTER, and I'm not going to argue with you, but instead you FLAT OUT call something you know NOTHING ABOUT and call it junk, and that is what sets me off. I don't hesitate to &quot;slam people&quot; when they start spouting off ignorant opinions.

Dude... If you want more respect HERE, actually READ what someone posts instead of SKIMMING IT and making wild ass assumptions.

Jon

 

[jonnyGURU]

BTW: In that thread that YOU SKIMMED that you say that I said &quot;any Taisol&quot;.... I said &quot;a Taisol&quot; and then said, &quot;Mind you I'm talking about the CEK734092. Taisol DEFINITELY has a better fan on the higher end.&quot;

If there's ANYTHING that's going to piss me off around here is people that quote me out of context and state opinions as facts and you hit me on BOTH accounts.

Thanks for raising my blood pressure. :|

<<

If the Dynatron is exactly like the stock AMD retail cooler (and it certainly looks like it) then he will be lucky to get down to 50C. I've watched a guy use the retail cooler on a stock 1.2 and he started out around 60C. With voltage adjustments and more case fans he got close to 55C. To me, that isn't acceptable no matter what AMD's site says. He broke down an ordered an MC-370A and with no other changes, it lowered his temps to 40C.

I wouldn't trust my $259 chip to a $9 cooler. To each his own I suppose. I guess that's why they make more than one HSF.

 

[WarCon]

I don't think a .79 C/W heatsink will work on an Athlon at even close to acceptable.

A 1ghz processor (~54watts at full load) with a .79 C/W heatsink will be running ~43C over the system temp (typically 30C) so the overall temp will be around 73C at full load. I have never been able to keep my processor stable at much over 55C on my KT7A (but thats thermistor measured so its probably higher). And at 1.4ghz (~81watts at full load) a .79 C/W heatsink would only cool it to ~64C over ambient or with a system temp of 30C you would be at 94C (1C below the absolute highest rating)

So that heatsink must have a better rating than the .79 C/W, because I don't think you could keep a system stable with full load temps that high.

 

[jonnyGURU]

If we all quote each other (or ourselves), maybe we can come to an agreement.



<< The retail fan pushes little to no air. It's horrible and I can't think of why AMD uses that unit. >>



We sell retail CPUs too. This is where I derive this &quot;opinion&quot;. I don't personally think the retail fan is &quot;adequate&quot;. Maybe if the fan produced more air, dunno. But, I'm not it's biggest &quot;fan&quot; (pun intended).

 

[WarCon]

Hey jonny, maybe you will know. But how does AMD rate what is good enough? I have built a few retail duron systems, that full load at 51-53C with the stock hsf. Was wondering what they consider acceptable running temps? I have looked at their site and never came away with an answer that was definite. By simple math though, with the heatsinks they ship with their processors they must be ok with 50-60C range. Maybe even higher.

And which causes more aging on the chip, heat or voltage?

 

[eLiu]

those CW readings are all relative to who tests'em. I mean, ive seen the Thermalright SK6 rated at .57 CW at once place....and .23 some where else. Now, that's a HUGE difference. I suppose one can only use each site as a reference- to find out which cooler they had perform the best...

neway, the place that gave Glacier2 was the one that gave SK6 .57...and the orbs .8+ *shudders at the thought of an orb*

neway, just to let y'all kno, jonny said (in my other thread) that his 1.4 w/dynatron runs at 60C, according to the (all too inaccuate) thermistor thingy

60C (give or take) isnt too awful; the cpu will live on until i get a better one (if i dont like the dyn)...besides, i can always open up the case and drop this 2ft diameter fan right next to it...more CFMs than you could ever dream of

-eric

 

[NightTrain]

60C is very hot. My ShutdownNow! is set at 50C.

 

[Adam12176]

In point of fact, if any heatsink was really .8 c/w, you would be looking at a puddle of aluminum on that processor. I think a block of wood is about .8 c/w (Not really, but you get my drift) I trust overclockers.com, they have a pretty nice uniform testbed for all their heatsinks, and the new radiate has it's own database which gives an accurate look at a ton of heatsinks.
Personally, I have had 2 cases of outright fraud from OCZ, and I wish they were here right now, so I could poke them with very pointy sticks. (Pretested Durons my arse)
Also, .3 c/w is what AMD reccomends as a MINIMUM as you start creeping up the MHz/GHz ladder. I still say Thermalright, just because it matches the 80 dollar swiftech unit. If you want to play at 1.5, you're going to have to pay.

And Johnny, I suggest you check out that article I keep posting about on overclockers.com I have a feeling there's something you're not telling us about your fabled 1 @ 1.4 with a crap cooler. I'll say it takes you 1.85 volts to keep it stable, just for experiments sake.So, your 1.4 radiates 80 watts of heat.I'll assume your room is moderate temperature wise, and I'll even say you have your case open, making it the same in and out. 30c. So, 80 watts x .35 (Also giving you the benifit of a doubt there)=28, and then add your case temp on top of that. (30c) and you get 58c. 2 degrees c under what most reccomend as a 'workable' temperature. I don't think that's exactly &quot;Running Cool.&quot; I'm not saying it doesn't work, but it's not great.
Same equation with Thermalright: 80x .19 = 15.2 + 30c = 45.2 Yea, I'd say that stock cooler is crap.

 

[yakko]

Garion,

My $150 CPU (Athlon 1.2@1.2)works fine with that fan you call a piece of junk. The temperature does not climb above 46 degrees Celcius. Part of this is because I have good case cooling as well. Obviously you have no idea what you are talking about. Not suprising since you defend your opinions with lies and misqoutes. Maybe you should go out and actually use the products that you are slamming so you can have accurate data. Until then though I will regard your comments as fecal matter suitable only to spread on the mushrooms.
