Thermalright 120 ultra from OC

[instinct]

Well, i've just received my third faulty replacement from OC for this particular model as the base is once again banana shaped after requesting it be checked before being send out :<

Bah, so!

What do people recommend instead of the TR120 that's less likely to be faulty?

 

[jak731]

if the base is cueved then maybe a lapping kit

alternatively a tuniq tower will be a worthy replacement if coolign a Overclocked quad

 

[ginjaninja]

if im planning to follow the lapping guidance on these forums anyways for T120 and q6600..is the T120 the reccomended cooler?

 

[Reality|Bites]

Does the TR 120A have the same problem as the Extreme version?

 

[instinct]

Cheers, yeah i think i'll go for tuniq, 3 faulty ones now from OC doesnt fill me with hope for a possible working one.

I've thought about lapping but to be fair on a brand new rig i just shouldnt have to do that :<

Cheers for the help guys.

I will be recieveing mine soon and will be lapping it out of the box, Intersesting to see if its quite as bad as you depict, 3 in a row? More than unlucky.

But are these HS surpossed to be concaved??, as a lot of CPU are said to be convex??

Surely it's a duff batch from production? That or seriously hard luck, which I doubt.

mine TRUE120 is very flat, at least i can't see any concaved inspection by eye, will test using a razor blade when i re-mount it later, probably next week.

it's probably just bad luck.

although you shouldn't expect them to open a product for you to see if it's good your not. i've went to OCuk and asked them to let me inspect a LG L226TWQ monitor for dead pixels, and they didn't allow me.

I'm not having a dig but with a known problem such as the irregular bases on these coolers I'd have thought it would be prudent inspect them all as they came into stock and reject any faulty ones back to my supplier. It is in their interests to avoid costly returns and in turn the customer gains confidence that when they order they are getting a good one - I bet a lot of people are put off buying one for this very reason.

 

[cavemanoc]

Yep - I was considering buying one - not anymore - word of mouth is a powerful force

 

[LewisStuart]

Lapping only takes 30mins, away and buy some wet & dry from halfords guys

 

[cavemanoc]

The point (for me) is that I shouldn't have to - if their industrial process is so poor that they can't achieve automatically, something we can by hand in 30 minutes, then their methods leave much to be desired - personally I'll spend my money with the guys who can finish the job properly

would you say that once youve made the lapping effort this cooler is as good as they come. dont mind 30 mins work...but if theres something better for less hassle...

I found this while researching this heatsink, it has a quote from the people at Thermalright, it seems ultra`s and extremes are manufactured this way

This fact has been confirmed to me, having checked a few when we had them in stock. Indeed, they all seem to be at least a bit concave. At first glance, this would lead you to believe there were some quality control issues going on, as the prevailing opinion is that flat = good.

I brought up this issue to our Thermalright rep today, and it turns out this is done intentionally, for two main reasons:

1 - As most of you know, the IHS on the chips are rarely perfectly flat, and tend to be slightly convex. Thus, convex IHS + concave HS gives a better contact, in general.

2 - The concave shape helps keep it from "sticking" to the IHS. Some of you may have had problems in the past, when the Heatsink is seated for any length of time. Sometimes it's hard to get it to release, and some have damaged processors this way. The concave shape of the base is supposed to help reduce this.


The actual benefit of shaping the base this way will likely still be debated by people, and you're obviously free to draw your own conclusions - but ultimately, the shape is not due to lack of quality control, it's an intentional design. Hopefully this helps clear up some of the frenzy!

Just as i said above then

 

[WarBird]

snip

i thought i read it's concave cause when they solder the heatpipes onto the base the heat warps it a little making it concave?

 

[helmutcheese]

TR talk a lot of BS, I have said it so have other engineers over on XS.

I posted this elsewhere and stand by it.:

TR are talking BS.

They cant make it concave very easy on purpose, and if they did it would be uniformed across all made.

It aint, some are concave, some are convex, all in different areas of base.

It is cause they solder the Pipes and it buckles the base, they should machine the base after Pipes are soldered.

Yeah I read that aswell ,can`t remember where though.The quote from my above post maybe a statement to cover up their shoddy manufacturing techniques.

Its a slightly older review,but no improvement over cooling after lapping.

Someone else here mentioned a bad Jig (Jig hold its in place when soldered).
