not as sad as this case study

meh case study 6

happened around 1 yr+ ago, where prolimatech are still hot... >.<
One customer approached me and wants to buy a CPU cooler, i asked and it's just a mere E5400 and he say he wanna OC a little up to 3ghz as stock fan OC 3ghz = noisy. So i recommended him a basic cooler (Gelid Silent Spirit) that fits just nicely in his casing, and yay~ happy customer, Until the NEXT day he come back
seller: Welcome back "Buyer", how's the cooler? (saw he bring his PC along to shop again)
Buyer: Oh my, the Cooler SUCKS, temps are so high (as in our aircond room, it shows only ~ 57+ when OC-ed to 3ghz), and When i try to OC to 3.5ghz, the TEMPS are soo HIGH, Why isit SO? Why recommend me SHIT product? bla bla bla >.<
So in this case, i wanna ask him out d, cos he never tell me he wanna OC till 3.5ghz. but he as a regular, i offered him to topup to get the CM Hyper 212+ that has two fans (Push / Pull) that will definately do the work. and Self Telan Gelid and keep for now. Top up, see temps, happy customer again.
3rd Day.... He came back.. and i am very moody that time... WHY HE COME BACK Again!
buyer: you ah (pointing @ me) Why you give me such a Laoya Product! the fan is SOOO loud (he go tweak his Bios Smartfan -> 100%) and i can't even enjoy my songs... Bla bla bla~ and it's not really Cooling my processor! based on a thread that it OC's to 4ghz With the same cooler to get a Bette results (he failed to notice the Ambient temp @ malaysia compared to other countries Ambient Temp)
So Being a Courteous Seller, and since i also moody, i just ask him to take the Best Air Cooler, that's the megahalems, and since he is a "Rich" customer, that sits a S class Merc to our shop, so this puny $$ is not a problem to him. I even asked him to get Water Cooling, but he rejected it as he scare water flow out despite it's Sealed ones (H60 / Coolit Domino anyone?) + 2 units of Silverstone fan FM-121 + FM-123 with controllable knobs so therefore he could choose when to tune up / tune down fan speed so therefore won't distrub his enjoyment with his songs... And despite the cooler cannot fit his casing, he say nvm, just don't cover the side casing will do. And refuse to change the case despite i offer him free Assembly charges of swapping cases. His problem>.<
so a total of 3 Swaps, hopefully nothing happens anymore as i am bored to see his face... Somemore 7 day 1-1 exg.. i feel like shouldn't tell him that... +_+
And 4th day, almost the same as the previous day But this time with a Spoiled knob. He told me that his Child was toying with the knobs, and ended up breaking it, and ask for replacement... Plus he say the results are not good, only can get good results when Crank the fan speed to the MAX, and definately it's NOISY
So i asked him, Are you sure you don't wanna change to Water Cooling? and at last he say, if it has almost the results of prolimatech + silent as silent spirit,Yes. And Topup + - out the spoiled fan controller , so he goes away, and that ends up my case... with this customer... no longer return UNTIL the 7th day.
7th day, last day of swapping, he come with a partially wet casing, and i was shocked on what happened on that... All equipments are Toasted, except the GPU. HE asked me to PAY HIM BACK ALL $$ + Buy another HAMSTER for HIM... (tbh the hamster for some reason was let loose, and bit the water hose, and got electrocuted due to the high power leak from the water...)
This time, being a bad seller, i just poilitely ask him out, and just ignore him as he is being too nosy, and idiotic at the same time.
So How you guys think on this? failure customer? or I Fail as a seller? Because i didn't ask him that if he has a HAMSTER in his house and recommended him a Sealed WC?
