Thermalright Ultra-120A Extreme (Help)

[WJA96]

Are you serious?

Certainly.

Couple of points, firstly show me a statement from Thermalright where they say running a TRUE without a fan is not recommended?

You've misunderstood me - what I said was that Thermalright made a better passive cooler, so why not buy that one?

Secondly I've used a *passive* TRUE in a few builds and it's fine . . . really it's fine unless you have a volcanic processor overclocked to the max!

It won't handle an i7 of any description, overclocked or not, but what you are saying is correct.

I really can't see a Passive True having problems with a stock to mild overclock chip in a well cooled case? . . . if it gets to hot then pop on a quiet fan but your not gonna bust anything experimenting with running Passive

Again, I didn't say differently (it certainly wasn't my intention to say differently).

I nearly bought the combo but being familiar with the Bolt-Thru-Kit I was aware it doesn't come with a hold-down plate and it looked the the supplied LGA771 bracket isn't the same dimensions so that was that!

The LGA775 bolt down kit does come with top and base brackets and 4 nice screws. It's the same retention mechanism you're using on the TRUE, actually.

The LGA775 bolt down kit does come with top and base brackets and 4 nice screws. It's the same retention mechanism you're using on the TRUE, actually.

I've bought and used half a dozen Thermalright LGA775 bolt-thru kits over the past year and they don't come with a hold-down clamp of any kind, just a backplate and four screws . .

All you do is stick on the backplate, remove the intel plastic push-pins and use the four supplied screws to attach the heatsink . . .

Since there is no hold-down clamp included in the Thermalright LGA775 bolt-thru kit I don't see how it can be used with a Thermalright HR-01X which is socket 771 and as far as I know socket 771 has different heatsink mounting holes to socket 775

I wanted a Thermalright HR-01 or HR-01 Plus but they do not appear to be for sale in the United Kingdom and haven't been for several months, therefore I cannot comment on their performance since they are vapourware. The only nearest alternative is the XEON fitting Thermalright HR-01X which as already explained does appear to be compatible with a Socket 775 system.

Because of all of the above I plumped for using the Thermalright Ultra-120 Extreme as a *passive* cooler. Yes I agree it's designed to run optimally with some kind of fan attached but I am please to confirm it cools rather well when running *passive*. As far as I am aware the TRUE is designed to be paired with High-Static-Pressure-Airflow and the HR-01 family is designed to run with Low-Static-Pressure-Airflow, this means that out of the two the TRUE will give the best cooling out the two is using a Powerful 120mm fan and the HR-01 family will give the best cooling when running *passive* or with a quiet 120mm fan that delivers gentle airflow.

Passive cooling is not a one size fits all solution but for people with good airflow in their cases, a 45nm micron undervolted/overclocked processor it works very well and in relative silence with a tad less electric consumed.

Sorry for the long reply and it feels like I am stating the obvious but all I did in this thread is reply to paul_31 who asked "Does anyone run the True without a fan attached? How do you think it would cope?"

I think the problem comes from the fact my answer was aimed at Socket 775 users and some people reading my reply assumed I was reffering to an overvolted/overclocked Intel® Core™ i7

I shall be more meticulous in my future posts to avoid any further mis-understandings!

I don't know why everything has to be such a challenge with you dude. No-one's giving you any grief over anything. Quite the opposite.

I have two new, unused, HR-01 S775 kits and they look like this;

As you can see they come with a clamp to match the indent in the base of the cooler (as posted by you). They come in a plain white box. The HR-01 as it originally supplied was AMD S939 only, so all the early ones had to have a spare S775 kit bought for them.

I honestly don't know why you can't get an HR-01, you can have one of mine if you like as I seem to be drifting towards water cooling for everything.

Now your taking the mick, I made a quick reply to another poster and I get you and another guy jumping on me saying "You can't do that" and "You have to do it like this" and "Thermalright say it's not recommended" etc etc

I'm talking about an actual product that I have actual experience of, you are talking about something not available to the general public for sale and that clamp doesn't even appear on the Thermalright website, so basically your whole contribution to this thread has been . .

"Don't buy the TRUE as a passive cooler, instead follow my recommendation for a better product that you can't buy!"

Great!

P.S welcome back from where ever you been, not the best of starts but . . .

 

[WJA96]

OK, I have no idea how you came to read all of that into my posts, but it certainly wasn't what was intended. If I have given any offence, I apologise wholeheartedly.

If it's any consolation I think I know how to get more clamps - I can break them down from S775 push-pin kits

if ya need a 775 clamp i got one spare as i bought the 1366 bolt through kit so i got the screws backplace and clamp going spare drop me an email

 

[Big.Wayne]

Yeah no worries WJA96, if you re read the thread it does seem like a few peeps jumping on the "That's not right" bandwagon when as we both no there is no hard and fast rules in this arena.

The Thermalright HR-01 Plus appears to be the ideal solution for *passive* overclockers and the spiritual successor to the old HR-01 (which has now gone EOL). If anyone can source a Thermalright HR-01 Plus for sale in the U.K then please let me know. Failing that the only option open as a high end *Passive* cooler is the HR-01X which blatently won't attach to an LGA775 platform, even using that bracket WJA96 posted above is likely to not fit as the newer heatsinks feature more heatpipes and would most likey need a scissor-action hold-down clamp to be able to fit through the base!

Some good has come from this thread, having just been pawing through the Thermalright website I notice this new bit of kit . . .

LGA775 Bolt-Thru-Kit Rev.2


That would appear to be compatible with the XEON/LGA771 Thermalright HR-01X, only trouble being this rev2.0 kit isn't available for sale yet heh!

new here and curious for some time,cant find on thermalright site too,need to know the measurement of the mounting holes of LGA 775 underbracket.

need to upgrade it on my Dell optiplex 755,curruntly using without the case.so ther will be no problem if the cooler fits on the screw holes on the board.OR I HAVE TO DRILL.lol

ambient temps are too high,like 35c+ .so upgrade is must.

currently doing 51-55c idle,68c+ load and eventualy have to shut down the pc to save hardware.stock speeds.my E8400 runs 2.0ghz on idle and hits 3.0ghz on load.considering 2.0ghz idle hiting 55c is not good.


here is what i need to know.

Hi wtfiswronge,

welcome to OcUK forums!

An E8400 at stock with a premium air cooler will idle at around 30°C and load at approx 44°C so your temps have scope for improvement!

I haven't got the dimensions of the Thermalright backplate but it will be the right size to fit the LGA775 socket!

Where the hell do i get a purple motherboard from?

lol i dont know,took this off while googling.

After searching i found this thread, and it kinda leads me to my next question.
I have a thermalright 120 ex but when i install it, it touches my dominator modules heat fins >.< since i only got a mounting kit for horizontal orientation in the box i cant use it. I emailed thermalright and they said that i need this kit;
http://www.thermalright.com/new_a_page/support/installation/am2_btk_rev2.htm

Do overclockers have any plans to get this in stock? i couldnt find it anywhere in the UK maybe somebody can help.

edit oops forgot to say what im running.

phenomII x4 955
crosshair III
4gb corsair domi

I am currently using a TRUE without a fan on an old Dual Core Athlon 6000+X2 system, and it is perfectly fine..

Idle temps are quite high, but when I put a load on it, the temps don't go up that much at all.

The reason I am running it without a fan is simply for quietness as the PC is in my bedroom, and is on 24/7.

 

[liquidex]

Even when running passive seems like the megahalems matches even the hr-01 plus. However if you are using an amd system you have to justify the extra cost of the amd bracket for a few degrees :/

What is the passive video card you use Big Wayne ?

That was a half height Radeon HD3450 I believe!

Thanks looking for a passive video card my self to cut down on noise. in my antec p180

 

[Big.Wayne]

Off Topic:

Well you have more choices now although the HD3450 will probably work out cheapest, I swapped the HD3450 out for a Passive HD4670 which while identical to the other card for desktop use was *hugely* better for some occasional gaming!

Thanks that could well do for me but at the moment still trying to decide i7 920 or i7 860 need to decide before saturday.
